Question 6

What is the sequence for searching bundles?

Answer 6

Step 1. The search starts by looking for an exact match for the resource bundle with the full name

Step 2. The last component (the part separed by _ ) is dropped and the search is repeated with the resulting shorter name. This process is repeated till the last locale modifier is left

Step 3. The search is restarted using the full name of the bundle for the default locale

Step 4. Search for the resource bundle with just the name of the bundle

Step 5. If search fails throw MissingBundleException
