java - 有没有办法获得随机整数的 Math.min() ？ java

Question

我目前正在制作一个游戏，我正在尝试比较屏幕上显示的最短路径(这是随机生成的整数路径)和用户采用的路径。这部分代码是我尝试获取屏幕上总路径的 Math.min() 的代码:

int path1 = randomNum3 + randomNum8;
int path2 = randomNum2 + randomNum7;
int path3 = randomNum + randomNum6;
int path4 = randomNum3 + randomNum5 + randomNum7;
int path5 = randomNum2 + randomNum5 + randomNum8;
int path6 = randomNum + randomNum4 + randomNum7;
int path7 = randomNum2 + randomNum4 + randomNum6;


int caminoMasCorto = Math.min(path1, path2, path3, path4, path5,
        path6, path7);

向我展示的错误是这个:

no suitable method found for min(int,int,int,int,int,int,int)

method Math.min(int,int) is not applicable

(actual and formal argument lists differ in length)

Answer 1

要查找多个 int 变量中的最小值，请使用:

int caminoMasCorto = IntStream.of(path1, path2, path3, path4, path5,
        path6, path7).min().getAsInt();

如果您没有使用 Java 8+，您可以执行以下操作:

int caminoMasCorto = path1;
for (int value : new int[] { path2, path3, path4, path5, path6, path7 })
    caminoMasCorto = Math.min(caminoMasCorto, value);
