所以我创建了一个程序,用y方向滚动z次x次,并且我在第一个for循环的第一行继续得到一个越界错误。但是我不确定为什么会这样,循环计数从0到(z-1)。我基本上处于这个程序的主页,我需要stackoverflow社区的帮助。
public class Ass11f {
public static void main(String[] args) {
EasyReader console = new EasyReader();
System.out.print("Enter how many times you want to roll the die: ");
int x = console.readInt();
System.out.print("Enter the amount of sides: ");
int y = console.readInt();
System.out.print("Enter the amount of die: ");
int z = console.readInt();
int[][] dice = new int[x][z];
int row = 0;
for (int i = 0; i<z; ++i){
dice[row][i] += ((int)(Math.random()*y)+1);
if ((i == z-1)&&(row!=x)) {
i = 0;
++row;
}
}
row = 0;
int[] sum = new int[x];
for (int j = 0; j<z; ++j){
sum[row]+=dice[j][row];
if ((j == z-1)&&(row!=x)) {
j = 0;
++row;
}
}
int[] counter = new int[2*y];
int k = 0;
while (k<sum.length){
for (int l = 0;l<((2*y)-1);++l){
if (sum[k]==l) ++counter[l];
if (l==((2*y)-1)) {
++k;
}
}
}
for (int m = 0;m<sum.length;++m) System.out.println(sum[m]+"'s: "+counter[m]+"times, "+((((double)counter[m])/x)*100)+"%");
}
}
答案 0 :(得分:0)
第一个循环:
for (int i = 0; i<z; i++){
dice[row][i] += ((int)(Math.random()*y)+1);
if ((i == z-1)&&(row!=x-1)) {
i = -1;
++row;
}
}
第二个循环:
for (int j = 0; j<z; j++){
sum[row]+=dice[j][row];
if ((j == z-1)&&(row!=x-1)) {
j = -1;
++row;
}
}
第三循环:永远运行。我不确定这是为了实现这个目标,所以我无法为你解决这个问题......
答案 1 :(得分:0)
有x行,但您使用z作为行循环
int[][] dice = new int[x][z]; <-- x is the row count
int row = 0;
for (int i = 0; i < z; ++i){ <--- The outer loop is iterating the rows (x),
以下是迭代2D数组的方法
int[][] dice = new int[x][z];
for (int i = 0; i < x; i++){
for (int j = 0; j < z; j++){
// do something with dice[i][j]
}
}
