Class Cast Exception Example in java

We are going to describe class cast exception in java. The class cast exception is a converting one data type into another data type. A Class cast exception is a thrown by java. In this example instances to handle class cast exception in a programs..Exceptions are the way in Java to indicate to a calling method that an unnatural condition has occurred.

In this example we have to convert one  data type into to another data type  by using castiing.

Vector vector = new Vector():-Creates a new vector.

Object obj = vector.add( a ):-Adds an integer type to the vector and stores in an object

To avoid this exception we have to add Integer a = new Integer((String)obj)

instead of String a = (String)obj.

Example

import java.util.Vector;


public class ClassCast {
	public static void main(String[] args) {
		
		  Vector vector = new Vector();
		  int a = 10;
		  Object obj = vector.add(a);
		  try {
		  String b = (String)obj;
		  vector.add(b);
		 } catch (ClassCastException e) {
		  System.out.println("Class cast exception: " + obj.getClass().getName());
		  e.printStackTrace();
		  }
		  }
		}
