Could you help me fix my code. and Explain what went wrong. Attempting to do a do while loop for sentinel input.

import java.util.Scanner;

public class SentinelWhileLoop {

public static void main(String[] args) {

//Create Scanner

Scanner input = new Scanner(System.in);

//Set up Variables for use

int MAX_VALUE = 0 ;

int MIN_VALUE = 0 ;

int sum = 0 ;

//Set up do while loop

do {

//Read in input from user

System.out.print(" Enter an integer: (Enter 0(Zero) to End) ") ;

data = input.nextInt() ;

//Replace Max and Min values if needed

else if (data < MIN_VALUE) {

MIN_VALUE = data ;

}

//Add to sum of data

sum += data;

//print out neccesary information

System.out.println(" Sum = " + sum) ;

System.out.println(" Largest Number =" + MAX_VALUE) ;

System.out.println("The sum is evem") ;

}

else {

System.out.println("The sum is off") ;
