Space out console text without tabs using Java

Question

Hey I am currently writing an expression calculator in Java. I have now got it to work but can't figure out how to space out writing in the terminal what I want is two list next to each other. I would originally of used tabs but because the arrays can grow it moves the other one. Here's what I get now:

OUTPUT BUFFER               STACK
[]                          []
[(]                         []

[(, +]                      [4]

Heres what I would like to achieve:

Heres the code I am currently using to print the stack and output buffer:

System.out.println("OUTPUT BUFFER\t\t\t\tSTACK");
ArrayList<String> out = new ArrayList<String>();
Stack<String> stack = new Stack<String>();
for(String token : inputTokens){
    System.out.print(stack+ "\t\t\t\t\t");
    System.out.println(out);
    if(isOperator(token)){
        while(!stack.empty() && isOperator(stack.peek())){
            if (checkPri(token, stack.peek())<=0 || checkPri(token, stack.peek()) < 0 ){
                out.add(stack.pop());
                //System.out.println("OUTPUT: " + out);
                continue;
            }
            break;
        }
        stack.push(token);

    }else if(token.equals("(")){
        stack.push(token);
    }else if(token.equals(")")){
        while(!stack.empty() && !stack.peek().equals("(")){
            out.add(stack.pop());
        }
        stack.pop();
    } else {
        out.add(token);
        //System.out.println("OUTPUT BUFFER: " + out);

    }
}

Answer 1

you can use String.format(String,args...) or System.out.printf(String,args...);

I don't know how to explain due to my poor english, but here the example:

int i=10000,j=200,k=5000000;
System.out.printf("%10d%10d%10d",i,j,k);

will get this output:

10000     200       5000000
^         ^         ^each has ten spaces between them because of %10d
