Java provides strong way to cope with Errors and Exceptions. When an illegal operation occurred Java throws exception. And When exception occurs program execution ends if exception is not handled properly. There is a class below to understand Java Exception..

 

public
class ExceptionExp1 {

 

    public
static
void main(String args[]){

        String strArray[] = {"This","is", "an", "example", "of", "Java","exception" };

        System.out.println(strArray[0]);

        System.out.println(strArray[1]);

        System.out.println(strArray[3]);

        System.out.println(strArray[4]);

        System.out.println(strArray[5]);

        System.out.println(strArray[6]);

        System.out.println(strArray[7]);

        System.out.println("Program will terminate before executing this line");

    }

}

 

If you execute this program, the output will be-
