ArrayIndexOutOfbound Exception occurs, when you assign an array which is not compatible with the data type of that array.

Example

public class ArrayoutofboundException {

  public static void main(String[] args) {
  try {
  System.out.println("args[0]="+args[0]);
  System.out.println("args[1]="+args[1]);
  System.out.println("args[2]="+args[2]);
  }
  catch(Exception ex){
  System.out.println(ex);
  }
  }
  }
