Format java string to show specific path

I'm new to Java and I have 4 built-in stacks that I need to print in a specific way. The IDE I'm using is BlueJ.

I want to print arrays so they look like this

 |110|   |231|   |333|   |444|
 |111|   |232|   |334|   |447|
 |112|   |233|   |335|   |448|
 |113|   |234|   |336|   |449|
 |114|   |235|   |337|   |450|
 |115|   |236|   |338|   |451|

I'm trying to do it with help System.out.println("|"+stack1.pop()+"|")

, but it creates a problem because I'm not sure how to go back, back. Ex. 115 -> back to 231. Each column represents a stack.

Thank!

Use String.format()

better than concatenating a sequence of strings

System.out.println(String.format("|%s|\t|%s|\t|%s|\t|%s|",
                            stack1.pop(),stack2.pop(),stack3.pop(),stack4.pop()));


If you want to print the items Stack

in reverse order, just reverse

stack first

You won't be able to do this in the console:
alternatively, you can print values ​​from each stack and then move down like:

System.out.println("|"+stack1.pop()+"|\t|"+stack2.pop()+"|\t|"+stack3.pop()+"|\t|"+stack4.pop()+"|" );


Edit as commented - you can use String.format (...) , check here for available formatting options

How about this:

    ArrayList<Stack<Integer>> arrays=new ArrayList<Stack<Integer>>();
    arrays.add(stack1);
    arrays.add(stack2);
    arrays.add(stack3);
    arrays.add(stack4);

//Put some code here to  Determine the stack size, if all are unequal in size   
    int size=stack1.size(); 


    for(int i=0;i<size;i++){
        String value="";
        String temp="";

// 4 = if you know how many stacks there will be only 4

        for(int j=0;j<4;j++){ 

            //Handle here Empty Stack Exception and print blank
            value="|"+(String)(arrays.get(j)).pop().toString()+"|"+" ";
            temp=temp+value;


        }

        System.out.println(temp);



    }
