Number Class intValue() method

  • intValue() method is available in java.lang package.
  • intValue() method is used to return the value denoted by this Number object converted to type int (by casting) and it may involve in rounding or truncations.
  • intValue() method is a non-static method, it is accessible with the class object only and if we try to access the method with the class name then we will get an error.
  • intValue() method does not throw an exception at the time of conversion from number to int.


    public abstract int intValue();


  • It does not accept any parameter.

Return value:

The return type of this method is int, it returns a converted (from type number to int) value represented by this Number object.


// Java program to demonstrate the example 
// of intValue() method of Number class

public class IntValueOfNumberClass {
    public static void main(String[] args) {
        // Variables initialization
        float f1 = 10.58f;
        double d1 = 20.62;

        // It returns int value denoted by this object
        // and converted to a int by calling f.intValue()
        Float f = new Float(f1);

        // Display f result
        System.out.println("f.intValue(): " + f.intValue());

        // It returns int value denoted by this object
        // and converted to a int by calling d.intValue()
        Double d = new Double(d1);

        // Display d result
        System.out.println("d.intValue(): " + d.intValue());


f.intValue(): 10
d.intValue(): 20
