Try with Finally Java (without Catch)


Generally, programmer writes try in combination with catch. Using finally block is optional. But it is possible to have try with finally without catch block) and compiler accepts clearly. Observe the following code.

Would you like read some more confusing concepts?

1. Why Java introduced StringBuilder with the same functionality (usage) of StringBuffer?

2. Why split() method was introduced when Java has already StringTokenizer?
Ans: StringTokenizer comes with JDK1.0 version where as split() method comes with JDK1.4 version. StringTokenizer beongs to java.util package and split() is defined in String class of java.lang package. One major difference is, split() supports regular expressions but StringTokenizer does not. If tokens (independent words) are required in an array form for easy retrieval and operation, split() is preferred. No operations on elements and only retrieval, StringTokenizer is preferred. It is jsut only coding requirements.

3. Can you code like this.

System.out.println(pow(2,4)); // Math class is not written

instead of traditional

System.out.println(Math.pow(2,4)); // Math is written
Ans: Yes, it is possible from JDK1.5 version with a new feature known as static imports.
