---

---

Description

The Java Integer valueOf(int i) method returns a Integer instance representing the specified int value i.

Declaration

Following is the declaration for java.lang.Integer.valueOf() method

public static Integer valueOf(int i)

Parameters

i − This is an int value.

Return Value

This method returns a Integer instance representing i.

Exception

NA

Example 1

The following example shows the usage of Integer valueOf(int i) method to get the Integer object using the specified int value. We've created a int variable and assigned it a positive int value. Then using valueOf() method, we're getting the object and printing it.

package com.tutorialspoint;
public class IntegerDemo {
   public static void main(String[] args) {
      int i = 170;
      System.out.println("Number = " + i);
    
      /* returns the Integer object of the given number */
      System.out.println("valueOf = " + Integer.valueOf(i));
   }
}

Output

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

Number = 170
valueOf = 170

Example 2

The following example shows the usage of Integer valueOf(int i) method to get the Integer object using the specified int value. We've created a int variable and assigned it a negative int value. Then using valueOf() method, we're getting the object and printing it.

package com.tutorialspoint;
public class IntegerDemo {
   public static void main(String[] args) {
      int i = -170;
      System.out.println("Number = " + i);
    
      /* returns the Integer object of the given number */
      System.out.println("valueOf = " + Integer.valueOf(i));
   }
}

Output

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

Number = -170
valueOf = -170

Example 3

The following example shows the usage of Integer valueOf(int i) method to get the Integer object using the specified int value. We've created a int variable and assigned it a zero value. Then using valueOf() method, we're getting the object and printing it.

package com.tutorialspoint;
public class IntegerDemo {
   public static void main(String[] args) {
      int i = 0;
      System.out.println("Number = " + i);
    
      /* returns the Integer object of the given number */
      System.out.println("valueOf = " + Integer.valueOf(i));
   }
}

Output

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

Number = 0
valueOf = 0
