Java - Double intValue() method



Description

The Java Double intValue() method returns the int value of this Double object.

Declaration

Following is the declaration for java.lang.Double.intValue() method

public int intValue()

Parameters

NA

Return Value

This method returns the int value represented by this object.

Exception

NA

Example 1

The following example shows the usage of Double intValue() method to get a int primitive value of given positive Double object. We've initialized a Double object with a given positive int value. Then using intValue() method, we're printing its value.

package com.tutorialspoint;
public class DoubleDemo {
   public static void main(String[] args) {
      Double d = new Double("15.30");
   
      //return the int value
      System.out.println("Value = " + d.intValue());
   }
} 

Output

Let us compile and run the above program, this will produce the following result −

Value = 15

Example 2

The following example shows the usage of Double intValue() method to get a int primitive value of given negative Double object. We've initialized a Double object with a given positive int value. Then using intValue() method, we're printing its value.

package com.tutorialspoint;
public class DoubleDemo {
   public static void main(String[] args) {
      Double d = new Double("-15.30");
   
      //return the int value
      System.out.println("Value = " + d.intValue());
   }
} 

Output

Let us compile and run the above program, this will produce the following result −

Value = -15

Example 3

The following example shows the usage of Double intValue() method to get a int primitive value of given negative Double object of zero value. We've initialized a Double object with a given positive int value. Then using intValue() method, we're printing its value.

package com.tutorialspoint;
public class DoubleDemo {
   public static void main(String[] args) {
      Double d = new Double("-0.0");
   
      //return the int value
      System.out.println("Value = " + d.intValue());
   }
} 

Output

Let us compile and run the above program, this will produce the following result −

Value = 0

Example 4

The following example shows the usage of Double intValue() method to get a int primitive value of given positive Double object of zero value. We've initialized a Double object with a given positive int value. Then using intValue() method, we're printing its value.

package com.tutorialspoint;
public class DoubleDemo {
   public static void main(String[] args) {
      Double d = new Double("+0.0");
   
      //return the int value
      System.out.println("Value = " + d.intValue()); 
   }
} 

Output

Let us compile and run the above program, this will produce the following result −

Value = 0
