Java Long toString() Method

Java toString() method is a part of the Long class of the java.lang package. This method returns the String object with its value equivalent to the signed decimal representation of the long value passed.This method overrides the toString() method of the Object class.

In short, this method is used to convert Long Object into String

Syntax:

public String toString()  

Parameters:

No parameters are passed in this method.

Returns:

Returns the String representation of the Long Object.

Example 1:

Here, the Long objects are converted into signed decimal representation and returned as a String.

import java.lang.Long;

public class StudyTonight
{  
	public static void main(String[] args) 
	{  
		Long a = 50L;       
		String s1 = a.toString();  // return a string value 
		System.out.println("Equivalent String is " + s1);              

		Long b = -18L;            
		String s2 = b.toString();  // return a string value 
		System.out.println("Equivalent String is " + s2);  
	}  
}


Equivalent String is 50
Equivalent String is -18

Example 2:

Here is a user-defined example where anyone using this code can put a value of his choice and get the equivalent output.

import java.util.Scanner;  

public class StudyTonight
{  
	public static void main(String[] args) 
	{  
		try
		{
			System.out.print("Enter the value ");  
			Scanner sc = new Scanner(System.in);  
			Long val = sc.nextLong();  
			String s = val.toString(); //converting to string
			System.out.println("String value is : "+ s);  
		}
		catch(Exception e)
		{
			System.out.println("Invalid input!!");
		}
	}  
}


Enter the value 755
String value is : 755
***************************
Enter the value -5889
String value is : -5889
***************************
Enter the value 0x588
Invalid input!!
