虽然循环没有运行，直到会议完成条件

Question

我创建了一个while循环，似乎无法正常运行。它会调用另一个类的方法来帮助更改我的程序的停止条件。它平均调用方法大约3-8次，永远不会达到停止条件，但会停止。

public class useExample 
    { 
    public static void main(String[] args) 
    { 

     Example ex = new Example(); 
     long [] result; 

     long a = 0; 
     long b = 0; 
     long c = 0; 
     long d = 0; 
     long e = 0; 
     int count = 0; 

     int a1 = 1; 
     int b1 = 2; 
     int c1 = 3; 
     int d1 = 4; 
     int e1 = 5; 


     for(int i = 0; i <1; i++) 
     { 
     while(a != a1 && b != b1 && c != c1 && d != d1 && e != e1) 
     { 
      result = ex.getOnes(); 
      a = result[0]; 
      b = result[1]; 
      c = result[2]; 
      d = result[3]; 
      e = result[4]; 

      System.out.println(result[0] + " " + result[1] + " " + result[2] + " " + result[3] + " " + result[4]); 

     System.out.println(a + " " + b + " " + c + " " + d + " " + e + " " + count++); 

     } 
     System.out.println(a + " " + b + " " + c + " " + d + " " + e + " "+ count); 

     } 



    } 
    } 

的实施例类是如下：

import java.util.*; 

public class Example 
{ 
    Random r = new Random(); 

    public long[] getOnes(){ 

     int a = r.nextInt(35); 
     int b = r.nextInt(35); 
     int c = r.nextInt(35); 
     int d = r.nextInt(35); 
     int e = r.nextInt(35); 

     while(a == 0) 
     { 
      a = r.nextInt(35); 
      //temp[0] = a; 
     } 

     while(b == 0 || b == a /*|| b == c || b == d || b == e*/) 
     { 
      b = r.nextInt(35); 
      //temp[1] = b; 
     } 

     while(c == 0 || c == a || c == b /*|| c == d || c == e*/) 
     { 
      c = r.nextInt(35); 
      //temp[2] = c; 
     } 

     while(d == 0 || d == a || d == b || d == c/*|| d == e*/) 
     { 
      d = r.nextInt(35); 
      //temp[3] = d; 
     } 

     while(e == 0 || e == a || e == b || e == c|| e == d) 
     { 
      e = r.nextInt(35); 
      //temp[4] = e; 
     } 

     return new long[] {a, b, c, d, e}; 
    } 

} 

的useExample类的while循环当同时的每个condtion是false.This应该只停止装置时：

a == a1 
b == b1 
c == c1 
d == d1 
e == e1 

它应该输出它经过的循环数以及每个循环的值。最终输出相同的a1值到e1。

Answer 1

“useExample类的while循环只应在while的每个条件为false时停止。”

使用 “& &” 而在（一个！= A1 & & b！= B1 & &！C = C1 & & d！= D1 & &电子！= E1）{...} 意味着，如果只有一个条件是错误的，例如（a！= a1）== false，整个条件将是错误的。

如果要循环运行，直到所有条件都为false，则应使用“||”而不是“& &”。 *
