Getting Long Object of a Positive long Value Example

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

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

Output

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

Number = 170
valueOf = 170

Getting Long Object of a Negative long Value Example

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

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

Output

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

Number = -170
valueOf = -170

Getting Long Object of a Zero Value Example

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

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

Output

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

Number = 0
valueOf = 0
