package UsingFinally;
class impFinally
{
public void FinallySemo()
{
int a[] = new int[2];
try{
System.out.println("Access element three :" + a[3]);
}
catch(ArrayIndexOutOfBoundsException e)
{
System.out.println("Exception thrown :" + e);
}
finally
{
a[0]=6;
System.out.println("First element value: " + a[0]);
System.out.println("The finally statement is executed");
}
}
}
public class ShowFinally
{
public static void main(String[] str)
{
impFinally obj=new impFinally();
obj.FinallySemo();
}
}
Output:
