java dicegolfgame-whileloop

我被这个while循环问题困住了，如果有人能指出我的错误，我会很高兴：

高尔夫游戏编写一个程序，使用while循环玩骰子高尔夫游戏。到洞的距离从100米开始。此人反复选择使用哪个俱乐部。每个不同的选择对应一个不同的虚拟“骰子”，即给出一个随机数。如果他们选择1号杆作为推杆，他们将掷0-5之间的数字，表示击球距离。如果他们选择2号球杆投球，他们的掷骰数为0-30。如果他们选择梅花3，他们会掷一个从0到150的数字。每次滚动后，从到孔的距离中减去该数字，下一轮负距离为正。它们一直滚动，直到距离精确到0。当他们这样做时，拍摄的照片数量会被打印出来

The following shows an example run of the program:
Distance to hole 100m. Which club (1-putting, 2-pitching or 3-iron) 3
You hit it...120m
Distance to hole 20m. Which club (1-putting, 2-pitching or 3-iron) 2
You hit it...16m
Distance to hole 4m. Which club (1-putting, 2-pitching or 3-iron) 1
You hit it...1m
Distance to hole 3m. Which club (1-putting, 2-pitching or 3-iron) 1
You hit it...3m
Congratulations. You took 4 shots.

我是java新手，下面是我设法完成的，但显示了错误：while input.equals！1 || 2 || 3 . 我不确定它是否做得正确，是否花了很多时间在这个问题上，如果有人能帮助解决这个问题，我会很高兴：非常感谢

是到球洞的距离决定了高尔夫球手是否需要再次投篮，所以应该在while循环中。我在代码中添加了一些注释：

String input = "";
int distance = 100;
int numberOfHits = 0;
int hit = 0;

while (distance > 0) {
    numberOfHits++;//increasing the nuber of hits
    input = JOptionPane.showInputDialog("distance to hole " + distance + " Which club (1-putting), 2-(pitching) or 3-iron");
    switch (input) {//if you don't know switch you coukd use if-else
        case "1":
            Random roll = new Random();
            hit = roll.nextInt(6);//a random int netween 0-5
            JOptionPane.showMessageDialog(null, "you hit ..." + hit + "m");
            distance -= hit;//sets the new distance to the old distance subtracted the hit
            distance = Math.abs(distance);//if distance is negative make it positive
            break;
        case "2":
            roll = new Random();
            hit = roll.nextInt(31);
            JOptionPane.showMessageDialog(null, "you hit ..." + hit + "m");
            distance -= hit;
            distance = Math.abs(distance);
            break;
        case "3":
            roll = new Random();
            hit = roll.nextInt(151);
            JOptionPane.showMessageDialog(null, "you hit ..." + hit + "m");
            distance -= hit;
            distance = Math.abs(distance);
            break;
    }
}
//when we are out of the loop the distance is zero
JOptionPane.showMessageDialog(null, "Congratulations, you took " + numberOfHits + " shots.");

while difference>0&&difference<0-这怎么可能？我不确定，因为我说我是新手，但问题是while循环即使差异为负值也要继续，所以我认为应该保持差异>0，并感谢您的帮助！！：这使它很容易理解，现在它更有意义了@尼罗斯

String input = "";
int distance = 100;
int numberOfHits = 0;
int hit = 0;

while (distance > 0) {
    numberOfHits++;//increasing the nuber of hits
    input = JOptionPane.showInputDialog("distance to hole " + distance + " Which club (1-putting), 2-(pitching) or 3-iron");
    switch (input) {//if you don't know switch you coukd use if-else
        case "1":
            Random roll = new Random();
            hit = roll.nextInt(6);//a random int netween 0-5
            JOptionPane.showMessageDialog(null, "you hit ..." + hit + "m");
            distance -= hit;//sets the new distance to the old distance subtracted the hit
            distance = Math.abs(distance);//if distance is negative make it positive
            break;
        case "2":
            roll = new Random();
            hit = roll.nextInt(31);
            JOptionPane.showMessageDialog(null, "you hit ..." + hit + "m");
            distance -= hit;
            distance = Math.abs(distance);
            break;
        case "3":
            roll = new Random();
            hit = roll.nextInt(151);
            JOptionPane.showMessageDialog(null, "you hit ..." + hit + "m");
            distance -= hit;
            distance = Math.abs(distance);
            break;
    }
}
//when we are out of the loop the distance is zero
JOptionPane.showMessageDialog(null, "Congratulations, you took " + numberOfHits + " shots.");
