Discussion :

The string valueOf(long l) method is simply to get a String equivalent of int method parameter. This method be statically accessed which means we should call the method like String.valueOf(long l).

Java Code Example :

This example source code demonstrates the use of valueOf(long l) of String class. Below are different examples of getting a value of long. As you would noticed we have used the unboxing functionality to transform a Long object into long primitive datatype and then get the string equivalent using the valueof method.

package com.javatutorialhq.java.tutorial.string;

/*
 * Java example source code to get the value of primitive long data type
 */

public class StringValueOfLong {

	public static void main(String[] args) {

		// primitive long declaration
		long val = 1;
		// Object of Long data type
		Long valueLong = 100l;
		System.out.println(String.valueOf(val));
		System.out.println(String.valueOf(valueLong));
		System.out.println(String.valueOf(1234567));
	}

}
