System.out.println("Your total is now " + total);

if(total == 100){
System.out.println("Congratulations, you WIN!");
break;
}
if (total > 100){
System.out.println("Sorry, you lose!");
break;
}

System.out.print("Another round? (Y or N): ");

char another = keyboard.next().charAt(0);
another = Character.toUpperCase(another);

if(another == 'Y'){
continue;
}

if(another == 'N'){
System.out.println("Goodbye! Sorry you don't like the game.");
break;
}   
}
}
}

import java.util.Random;

public class Coin{

int value;
String sideUp;

public Coin(int value){
  
if(value == 25 || value == 10 || value == 5){
value = value;
}
else
value = 1;
}

public void toss(){

Random rand = new Random();
int side = rand.nextInt(2);
  
if(side == 1){
sideUp = "HEADS";
}
if(side == 0){
sideUp = "TAILS";
}
}
public String getSideUp(){
return sideUp;
}
public int getValue(){
return value;
}
}

When the program is ran the value is not returned so 'total' stays at 0 and I can't figure out why

Here is the code.
//File: Client.java (no change)

import java.util.Scanner;
public class Client{
public static void main(String args[]){
Coin quarter = new Coin(25);

Scanner keyboard = new Scanner(System.in);
int i = 0;
int total = 0;
while(true){
i++;
System.out.println("Round " + i + ": ");
quarter.toss();
System.out.println("Quarter is " + quarter.getSideUp());
if(quarter.getSideUp() == "HEADS")
total = total + quarter.getValue();
dime.toss();
System.out.println("Dime is " + dime.getSideUp());
if(dime.getSideUp() == "HEADS")
total = total + dime.getValue();
nickel.toss();
System.out.println("Nickel is " + nickel.getSideUp());
if(nickel.getSideUp() == "HEADS")
total = total + nickel.getValue();
System.out.println("Your total is now " + total);
if(total == 100){

break;
}
if (total > 100){
System.out.println("Sorry, you lose!");

System.out.print("Another round? (Y or N): ");
char another = keyboard.next().charAt(0);
another = Character.toUpperCase(another);
if(another == 'Y'){
continue;
}
if(another == 'N'){
System.out.println("Goodbye! Sorry you don't like the game.");
break;
}
}
}
}

//File: Coin.java

import java.util.Random;
public class Coin{
int value;
String sideUp;
public Coin(int value){
if(value == 25 || value == 10 || value == 5){
this.value = value; //replaced value = value with this.value = value;
}
else
value = 1;
}
public void toss(){
Random rand = new Random();
int side = rand.nextInt(2);
if(side == 1){
sideUp = "HEADS";
}
if(side == 0){
sideUp = "TAILS";
}
}
public String getSideUp(){
return sideUp;
}
public int getValue(){
return value;
}
}

And here is the output when you execute the code
