如何以最有效的方式在屏幕上打印3个堆栈，每列7个

Question

我很难想出一个方法，把三个堆栈打印到屏幕上的3列7。基本上就像纸牌游戏。

/**
 * Prints the cards to the screen.
 */
private void printTrick() {


    for (int i = 0; i < bigStack.size(); i++){
        leftStack.push(bigStack.pop());     
        middleStack.push(bigStack.pop());    
        rightStack.push(bigStack.pop());   
    }

    for (int j = 0; j < 7; j++){
        System.out.print(leftStack.elementAt(j) + "\t");
        System.out.print(middleStack.elementAt(j) + "\t");
        System.out.print(rightStack.elementAt(j) + "\t");
        System.out.println();
    }
}

/**
 * Prints the cards to the screen.
 */
private void printTrick() {


    int i=0;

    while(i<21)
    {
        left.push(bigStack.pop());
        i++;
        middle.push(bigStack.pop());
        i++;
        right.push(bigStack.pop());
        i++;
    }

    for (int j = 0; j < 7; j++){
        System.out.print(leftStack.elementAt(j) + "\t");
        System.out.print(middleStack.elementAt(j) + "\t");
        System.out.print(rightStack.elementAt(j) + "\t");
        System.out.println();
    }
}

System.out.println（LeftStack.ElementAt(j)+MiddleStack.ElementAt(j)+RightStack.ElementAt(j)）；

抱歉，如果这看起来很琐碎，我不是一个很强的程序员，但任何帮助将非常感谢。谢谢

for (int i = 0; i < bigStack.size(); i++){

for (int i = 0; i < bigStack.size()/3; i++){
