Question

我想要特定条件的动态输出，我的条件是：

size = 3;
countersize = 8; //can be anything based on the user input.

如果我得到的反对为4或5或8，那么对于特定的反量化，我的输出应该是0或1或2中的任何一个。输出应该是＆lt; 3.

例1：

     **user Input:** countersize=7 then   output= 0 or 1 or 2 (only one from these) 
     **user Input:** countersize=5 then   output= 0 or 1 or 2 (only one from these)
     **user Input:** countersize=3 then   output= 0 or 1 or 2 (only one from these)
     **user Input:** countersize=0 then   output=0
     **user Input:** countersize=1 then   output=1
     **user Input:** countersize=2 then   output=2
     **user Input:** countersize=4 then   output= 0 or 1 or 2 (only one from these)
     **user Input:** countersize=9 then   output= 0 or 1 or 2 (only one from these)

示例2： 假设size = 2;和countersize = 8; //可以是基于用户输入的任何内容。

     **user Input:** countersize=7 then   output= 0 or 1 or 2 (only one from these) 
     **user Input:** countersize=5 then   output= 0 or 1 or 2 (only one from these)
     **user Input:** countersize=3 then   output= 0 or 1 or 2 (only one from these)
     **user Input:** countersize=0 then   output=0
     **user Input:** countersize=1 then   output=1
     **user Input:** countersize=2 then   output=0 or 1 or 2 (only one from these)
     **user Input:** countersize=4 then   output= 0 or 1 or 2 (only one from these)
     **user Input:** countersize=9 then   output= 0 or 1 or 2 (only one from these)

请帮我解决我的Java代码。

Answer 1

试试这个，它适用于你的例子：

public static int getOutput(int size, int countersize) {
    if(countersize < size) {
        // return the countersize value if it is inferior to size
        return countersize;
    } else {
        // return a value from {0, 1, 2}
        Random generator = new Random(); 
        return generator.nextInt(3);
    }
}
