I need help debugging this code, I have tried multiple times and still am having trouble please help.

Question

My assignment is to debug this code, however I am not sure about what I am doing wrong.

import java.util.*;

public class DebugFive4

{

public static void main (String args[])

{

Scanner input = new Scanner(System.in);

int one, two, three, four;

String str, output;

System.out.println("Enter an integer");

str = input.next();

one = Integer.parseInt(str);

System.out.println("Enter an integer");

str = input.next();

two = Integer.parseInt(str);

System.out.println("Enter an integer");

str = input.next();

three = Integer.parseInt(str);

System.out.println("Enter an integer");

str = input.next();

four = Integer.parseInt(str);

if(one > two > one > three > one > four)

output = "Highest is " + four;

else

if(two > one && two > three !! two > four)

output = "Highest is " + three;

else

if(three > one && three > two && three > four)

output = "Highest is " + three;

else

output = "Highest is " + four;

System.out.println(output);

}

}

}

import java.io.*;

class SortMax

{

private int A[];

{

A = new int[4];

for (int iLoop=0; iLoop<4; iLoop++)

{

}

}

String inbuff = console.readLine();

A[iLoop] = Integer.parseInt(inbuff);

}

}

{

int iTemp = A[jLoop+1];

A[jLoop+1] = A[jLoop];

A[jLoop] = iTemp;

} //swap

} //for jLoop

} //for iLoop

}

public void Go()

{

this.Input();

this.Sort();

System.out.println(" the max is " + A[3]);

System.out.println(" the min is " + A[0]);

System.out.println(" sorted list increasing :");
