Is it necessary that a try block should be followed by a catch block in Java?

Not necessarily catch, a try must be followed by either catch or finally block.

Example

 import java.io.File; public class Test{ public static void main(String args[]){ System.out.println("Hello"); try{ File file = new File("data"); } } } 

Output

 C:\Sample>Javac Test.java Test.java:5: error: 'try' without 'catch', 'finally' or resource declarations try{ ^ 1 error
