java - 如何运行多个 if 语句

Question

当我运行这段代码时，它只会执行一些 if 语句，直到找到一个为真的语句。如何让它贯穿所有的 if 语句。

for (int c = 0; c <= 9; c++) {
    for (int r = 0; r <= 9; r++) {
        try {
            if (Sprite.mine_1[c - 1][r - 1] < 20) Sprite.count++; //top left
            System.out.println("if 1");
            if (Sprite.mine_1[c - 1][r] < 20) Sprite.count++; //left
            System.out.println("if 2");
            if (Sprite.mine_1[c - 1][r + 1] < 20) Sprite.count++;  //buttom left
            System.out.println("if 2");
            if (Sprite.mine_1[c][r + 1] < 20) Sprite.count++;  //buttom    
            System.out.println("if 4");
            if (Sprite.mine_1[c + 1][r + 1] < 20) Sprite.count++;  //buttom right  
            System.out.println("if 5");
            if (Sprite.mine_1[c + 1][r] < 20) Sprite.count++;  // right    
            System.out.println("if 6");
            if (Sprite.mine_1[c + 1][r - 1] < 20) Sprite.count++;  // right to
            System.out.println("if 7");
            if (Sprite.mine_1[c][r - 1] < 20) Sprite.count++;  //top
            System.out.println("if 8");
        } catch (ArrayIndexOutOfBoundsException exception) {
        }
    }
}

我刚刚结束了很长的路要走。

        }
