Getting String Representation of a Positive long Value Example

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

package com.tutorialspoint;
public class LongDemo {
   public static void main(String[] args) {
      Long i = new Long(20L);
   
      // returns a string representation of the long value in base 10
      String retval = i.toString();
      System.out.println("Value = " + retval);
   }
}

Output

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

Value = 20

Getting String Representation of a Negative long Value Example

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

package com.tutorialspoint;
public class LongDemo {
   public static void main(String[] args) {
      Long i = new Long(-20L);
   
      // returns a string representation of the long value in base 10
      String retval = i.toString();
      System.out.println("Value = " + retval);
   }
}

Output

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

Value = -20

Getting String Representation of a Zero Value Example

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

package com.tutorialspoint;
public class LongDemo {
   public static void main(String[] args) {

      Long i = new Long(0L);
   
      // returns a string representation of the long value in base 10
      String retval = i.toString();
      System.out.println("Value = " + retval);
   }
}

Output

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

Value = 0
