Android - 如何简化十的倍数？

Question

我想要这样的多个值：

if (currentScore == 10 | currentScore == 20 | currentScore == 30 | currentScore == 40 | currentScore == 50 | currentScore == 60
            | currentScore == 70 | currentScore == 80 | currentScore == 90 | currentScore == 100 | currentScore == 110
            | currentScore == 120 | currentScore == 130 | currentScore == 140 | currentScore == 150 | currentScore == 160
            | currentScore == 170 | currentScore == 180 | currentScore == 190 | currentScore == 200) {
        editor.putInt("TOP_LEVEL", topLevel + 1);
        editor.apply();
    }

如何简化该代码以便计算多个 currentScore。 谢谢

Answer 1

使用 Java % operator:

if (currentScore % 10 == 0) {
    editor.putInt("TOP_LEVEL", topLevel + 1);
    editor.apply();
}

%运算符returns余数。如果 "currentScore" 除以 10 的余数为 0，则表示 currentScore 是 10 的整数倍。

Answer 2

int j = 10;

for (int i = 1; i <= 20 ; i++) {
     if (currentScore == j) {
         editor.putInt("TOP_LEVEL", topLevel + 1);
         editor.apply();
         break;
     }
     j = j + 10;
}
