Explain try and catch exception in java?

Java throws Exception objects to denotes a problem. These cannot be ignored.try-catchtry-catch public class HelloThere {
public static void main(String[] args) { try { System.out.println("Hello " + args[0]); } catch (ArrayIndexOutOfBoundsException e) { System.out.println("Hello Whoever you are."); }
}
