是否可以根据Java中的用户输入进行嵌套循环?例如,如果用户输入3,则有3个嵌套循环(3个循环级别)。如果有可能,你能告诉我怎么做吗?
我需要它来产生某种东西的可能性。每个循环发生两次。所以有2 ^ n种可能性。
感谢您的大力帮助。
修改 我还没有对循环计算部分进行编码,因为我还在试图找出算法。 的 Kriteria.java
public class Kriteria {
String name;
int min, max;
double lowMembership, highMembership;
public Kriteria(String name, int min, int max,low,high) {
this.name = name;
this.min = min;
this.max = max;
this.lowMembership = low;
this.highMembership = high;
}
}
MainClass.java
public class MainClass {
/**
* @param args the command line arguments
*/
public static void main(String[] args) {
ArrayList<Kriteria> listKriteria = new ArrayList();
//later on the user can decide how many kriteria he wanted and create them
Kriteria kriteria1,kriteria2,kriteria3;
kriteria1 = new Kriteria("Kriteria 1", 1, 10, 4,3,5);
listKriteria.add(kriteria1);
kriteria2= new Kriteria2("Kriteria 2", 5, 20, 13,7,18);
listKriteria.add(kriteria2);
kriteria3 = new Kriteria3("Kriteria 3", 3, 8, 5,4,7);
listKriteria.add(kriteria3);
/* I want something like this:
1st
double result= Kriteria1.lowMembership + Kriteria2.lowMembership + Kriteria3.lowMembership;
2nd
double result= Kriteria1.lowMembership + Kriteria2.lowMembership + Kriteria3.highMembership;
3rd
double result= Kriteria1.lowMembership + Kriteria2.highMembership + Kriteria3.highMembership;
and so on for each possibility...
*/
}
}
够了吗?我稍微更改了命名和机制以缩短
答案 0 :(得分:1)
你不能在运行时生成代码,因为这种问题只是去递归。
void fun(int n)
{
if(n==0)
return;
System.out.println(n);
fun(n-1);
}
