---

Description

The Java Long intValue() method returns the value of this Long as a int.

Declaration

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

public int intValue()

Parameters

NA

Return Value

This method returns the numeric value represented by this object after conversion to type int.

Exception

NA

Example 1

The following example shows the usage of Long intValue() method to get int value from an Long object. We've created a Long variable and assign it a Long object containing a positive long number. Then using intValue method, we're obtaining the int value from this object and then printed it.

package com.tutorialspoint;
public class LongDemo {
   public static void main(String[] args) {
      Long obj = new Long(5L);
 
      // returns the value of this Long as a int
      int i = obj.intValue();
      System.out.println("Value of i = " + i);
   }
}

Output

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

Value of i = 5

Example 2

The following example shows the usage of Long intValue() method to get int value from an Long object. We've created a Long variable and assign it a Long object containing a negative long number. Then using intValue method, we're obtaining the int value from this object and then printed it.

package com.tutorialspoint;
public class LongDemo {
   public static void main(String[] args) {
      Long obj = new Long(-5L);
 
      // returns the value of this Long as a int
      int i = obj.intValue();
      System.out.println("Value of i = " + i);
   }
}

Output

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

Value of i = -5

Example 3

The following example shows the usage of Long intValue() method to get int value from an Long object. We've created a Long variable and assign it a Long object containing a zero value. Then using intValue method, we're obtaining the int value from this object and then printed it.

package com.tutorialspoint;
public class LongDemo {
   public static void main(String[] args) {
      Long obj = new Long(0L);
 
      // returns the value of this Long as a int
      int i = obj.intValue();
      System.out.println("Value of i = " + i);
   }
}

Output

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

Value of i = 0

Example 4

The following example shows the usage of Long intValue() method to get int value from an Long object. We've created a Long variable and assign it a Long object containing a negative zero value. Then using intValue method, we're obtaining the int value from this object and then printed it.

package com.tutorialspoint;
public class LongDemo {
   public static void main(String[] args) {
      Long obj = new Long(-0L);
 
      // returns the value of this Long as a int
      int i = obj.intValue();
      System.out.println("Value of i = " + i);
   }
}

Output

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

Value of i = 0
