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 a long variable and assigned it a positive long value. Then using toString() method, we're printing the result.

package com.tutorialspoint;

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

Output

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

Number = 170
toString = 170

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 a long variable and assigned it a negative long value. Then using toString() method, we're printing the result.

package com.tutorialspoint;

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

Output

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

Number = -170
toString = -170

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 a long variable and assigned it a zero value. Then using toString() method, we're printing the result.

package com.tutorialspoint;

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

Output

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

Number = 0
toString = 0
