英文:
printing out stack without []
问题
以下是您要求的代码部分的翻译结果：
private int numberOfDisks;private int startPillar;private int targetPillar;private int extraPillar;private Stack<Integer>[] pillars = new Stack[3];private int steps;public Hanoi(int n, int start, int target) {numberOfDisks = n;startPillar = start - 1;targetPillar = target;extraPillar = 6 - start - target;steps = 0;pillars[0] = new Stack<Integer>();pillars[1] = new Stack<Integer>();pillars[2] = new Stack<Integer>();for (int i = n; i > 0; i--) {pillars[startPillar].push(i);}printStep();}private void printStep() {for (int i = 1; i < 4; i++) {System.out.print("t" + steps + " Pillar" + i + ": ");if (!pillars[i - 1].isEmpty()) {boolean first = true;for (Integer disk : pillars[i - 1]) {if (!first) {System.out.print(" ");}System.out.print(disk);first = false;}}System.out.println();}}
请注意，我对代码进行了必要的调整，以便输出与您所需的格式匹配。
英文:
When I print the stack I want it without [] braces.
What should I change in my code or how can I do it so the output looks like the one that I show below?
here is my output now
t0 Pillar1: [3, 2, 1]t0 Pillar2: []t0 Pillar3: []
I want it to be:
t0 Pillar1: 3 2 1t0 Pillar2:t0 Pillar3:
here is my code
private int numberOfDisks;private int startPillar;private int targetPillar;private int extraPillar;private Stack<Integer>[] pillars = new Stack[3];private int steps;public Hanoi(int n, int start, int target){numberOfDisks = n;startPillar = start-1;targetPillar = target;extraPillar = 6 - start - target;steps = 0;pillars[0] = new Stack<Integer>();pillars[1] = new Stack<Integer>();pillars[2] = new Stack<Integer>();for(int i = n; i > 0; i--){pillars[startPillar].push(i);}printStep();}private void printStep(){for(int i=1;i<4;i++){System.out.println("t"+steps+" " + "Pillar" + (i) + ": " + pillars[i-1]);}}

IMO 最快的方法是先将其放入一个字符串中String result = pillars[i-1];result = result.replace("[", "").replace("]", "");System.out.println("t" + steps + " " + "Pillar" + (i) + ": " + result);
英文:
IMO the quickest way would be to put it in a String first
String result = pillars[i-1];result = result.replace ("[", "").replace("]", "");System.out.println("t"+steps+" " + "Pillar" + (i) + ": " + result);

使用 Arrays.toString()：
System.out.println(Arrays.toString(pillars.toArray()).replace("[","").replace("]",""));
英文:
Use Arrays.toString():
System.out.println(Arrays.toString(pillars.toArray()).replace("[","").replace("]",""));</details>
