_____ are used to carry out specific actions
and are sometimes called functions.
Methods
Methods are used to carry out specific actions
and are sometimes called ________.
functions
In Java, a method runs only when it is called from
another ________.
method
The _______ is the starting point of a Java
program, and it is the first method executed by
the JVM (Java Virtual Machine).
main() method
The main() method is the starting point of a Java
program, and it is the first method executed by
the _______________.
JVM (Java Virtual Machine)
Methods in Java are ________________ designed to perform specific tasks.
reusable blocks of
code
They help break 1.____, 2._________ into 3._________, easier-to-handle parts
1.large
2.complex programs
3. smaller
_________ are used to compare two values
or variables.
Relational operators
Relational operators are used to compare 1.________
or 2.________.
- two values
- variables
They return a _______ result: true or false.
Boolean
They return a Boolean result: _________.
true or false
These operators are commonly used in________________ like if, while, and for.
decision-making statements
These operators are commonly used in decision-making statements like ___________.
if, while, and for
______ can be of any numeric type (int, double, etc.) or even Strings/Text (for == and !=).
Operands
__________ are binary operators (they work
with two operands).
Relational operators
Relational operators are __________ (they work
with two operands).
binary operators
_________________ are used to combine multiple
conditions or expressions.
Logical operators
Logical operators are used to combine 1.___________ or 2._________.
1.multiple conditions
2.expressions
Returns true only if both conditions are true.
&& (Logical AND)
Returns true if at least one condition is true.
|| (Logical OR)
Reverses the result of a condition.
! (Logical NOT)
For 1.__, if the first condition is 2.__-e, the second condition is not evaluated.
1.&&
2.fals
For 1.___, if the first condition is true, the second condition is not evaluated.___
- ||
2.true
____________ are used to make decisions in a program based on certain conditions.
Selection statements
Selection statements are used to __________ in a program based on certain conditions.
make decisions
They allow the program to 1.________________________ depending on whether a condition is ___________.
1.execute specific blocks of code
2.true or false
1.______________ are essential for controlling the 2._______.
1.Selection statements
2.flow of a program
1.________________: Executes a block of code if a specified condition is true.
Also known as 2.________ statement
1.if Statement
2.“if-then”
A shorthand for if-else that returns a value based on a condition.
Ternary Operator (? :):
1.__________________: Executes one block of code if the condition is 2._____and another block if the condition is 3.______
1.if-else Statement
2.true
3.false
Used to test multiple conditions in sequence.
The first condition that evaluates to true will have its block executed.
if-else-if Ladder
Used to select one of many code blocks to execute based on the value of a variable or expression.
Switch Statement
__________ keyword is used to terminate the switch statement.
break
break keyword is used to terminate the _____________.
switch statement
When a 1.___________ is encountered, the program exits the 2._________ and continues executing the code after the 3.____________.
1.break statement
2.switch block
3.switch statement
If break is omitted, the program will fall through to the next case (or default) and execute its code, even if the condition doesn’t match. This is called ________________.
fall-through behavior
The __________ keyword is used to define a block of code that executes when none of the case values match the switch expression.
default
The default keyword is used to define a block of code that executes when 1.____________ match the 2.__________.
1.none of the case values
2.switch expression
It is ___________, but it is good practice to include a default case to handle unexpected or invalid values.
optional
An if statement inside another if statement.
Nested if Statements
An if-else statement inside another if or else block.
Nested if-else Statements
An if-else-if ladder inside another if, else, or else-if block.
Nested if-else-if Ladder
A switch statement inside another switch
statement.
Nested switch Statements
1._______________ allow you to execute a block of code repeatedly as long as a specified condition is 2.___. They help reduce code redundancy and make programs more efficient.
Looping statements
2.true
Looping statements allow you to execute a block of code repeatedly as long as a specified condition is true. They help reduce 1._________ and make programs 2.___________.
1.code redundancy
2.more efficient
The _____ used when you know how many times you want to repeat a block of code.
For loop
___________: Executed once at the
beginning. It is used to initialize the loop
variable.
Initialization
____________: Evaluated before each
iteration. If true, the loop continues; if false,
the loop ends.
Condition
_______: Executed after each iteration. It
updates the loop variable.
Update
The ___________ is used when you want to repeat a block of code as long as a condition is true. The number of iterations is not fixed.
while loop
The while loop is used when you want to repeat a block of code as long as a condition is true. The number of _____________ is not fixed.
iterations
The _______ is similar to the while loop, but it guarantees at least one execution of the loop body, even if the condition is false.
Do-while Loop
_____________ - You can omit the initialization part if the loop variable is already initialized outside the loop.
Omit Initialization
- _____________ - You can omit the condition, but this will create an infinite loop unless you use a 2.__________________ to exit the loop.
1.Omit Condition
2.break statement
__________ - You can omit the update part and handle the update inside the loop body.
Omit Update
__________________________ - You can initialize and update multiple variables in the for loop.
Multiple Variables in Initialization and Update
________ - You can create an infinite loop by omitting all three components. This is useful in scenarios where the loop should run indefinitely until a break statement is encountered.
Infinite Loop
____________ - An infinite loop runs indefinitely until it is explicitly stopped (e.g., using a break statement).
Infinite while Loop
A ___________ consists of an outer loop and one or more inner loops. The inner loop completes all its iterations for each iteration of the outer loop
nested for loop
A ______________ consists of an outer loop and one or more inner loops. The inner loop completes all its iterations for each iteration of the outer loop.
nested while loop
