Question

我正在编写一个java代码来编写一个文本文件，我正在打印输出以查看是否所有条件都正确，有些情况下输出是正确的，而某些情况对于相同的条件是不正确的。案例是：

bpup >= 14  => out1 = 0  out 2 = 0

bpdown >= 9 => out1 = 0 out 2 = 1

bpup > 14 and bpdown > 9 => out1 = 1 out2 = 0 

bpup > 14 and bpdown > 9 and pulse <60 => out1 = 1 out2 = 1

这是我的代码：

package pfetext;

import java.io.BufferedWriter;
import java.io.FileWriter;
import java.io.IOException;
import java.util.Random;

/**

public class PFEtext {

    /**
     * @param args the command line arguments
     */

    static int i = 10;
    static int out1;
    static int out2;

    public static void main(String[] args) throws IOException {
        // TODO code application logic here
    int bpup;
    int bpdown;
    int pulse;
    int O2;    
         FileWriter fw=new FileWriter("C:\\Users\\user\\Desktop\\pfe.txt"); 
         BufferedWriter bw= new BufferedWriter(fw); 
         do {
         Random p = new Random();
         bpup = p.nextInt(23 - 3) + 3 ;
         bpdown = p.nextInt(17 - 4) + 4 ;
         pulse = p.nextInt(150 - 30) + 30 ;
         O2 = p.nextInt(100 - 40) + 40;

         //Epistaxis
         if(bpup >= 14){
         out1 = 0;
         out2 = 0;
         System.out.println("========== CASE EPISTACSIS ==========");
         System.out.println("BPUP " + bpup + " " + "BPDOWN " + bpdown + " " + "PULSE " + pulse + " " + "OUT1 " + out1 + " " + "OUT2 " + out2);
//         bw.write(bpup + "," + bpdown + "," + pulse + "," + O2 + "," + out1 + "," + out2);
//         bw.newLine();
         }

         //Blackout
         if(bpdown >= 9){
         out1 = 0;
         out2 = 1;
         System.out.println("========== CASE BLACKOUT ==========");
         System.out.println("BPUP " + bpup + " " + "BPDOWN " + bpdown + " " + "PULSE " + pulse + " " + "OUT1 " + out1 + " " + "OUT2 " + out2);
//         bw.write(bpup + "," + bpdown + "," + pulse + "," + O2 + "," + out1 + "," + out2);
//         bw.newLine();
         }

         //Epistaxis and Blackout
         if(bpup >= 14 && bpdown > 9){
         out1 = 1;
         out2 = 0;
         System.out.println("========== CASE EPISTACSIS & BLACKOUT ==========");
         System.out.println("BPUP " + bpup + " " + "BPDOWN " + bpdown + " " + "PULSE " + pulse + " " + "OUT1 " + out1 + " " + "OUT2 " + out2);
//         bw.write(bpup + "," + bpdown + "," + pulse + "," + O2 + "," + out1 + "," + out2);
//         bw.newLine();
         }

         //Numbness
         if(bpup >= 15 && bpdown >= 9 && pulse <= 60){
         out1 = 1;
         out2 = 1;
         System.out.println("========== NUMBNESS ==========");
         System.out.println("BPUP " + bpup + " " + "BPDOWN " + bpdown + " " + "PULSE " + pulse + " " + "OUT1 " + out1 + " " + "OUT2 " + out2);
//         bw.write(bpup + "," + bpdown + "," + pulse + "," + O2 + "," + out1 + "," + out2);
//         bw.newLine();
         } 
         i--;
         }while(i>0);


         bw.write(bpup + "," + bpdown + "," + pulse + "," + O2 + "," + out1 + "," + out2);
         bw.newLine();

         bw.close();      
    }

}

这是输出：

========== CASE BLACKOUT ==========
// correct
BPUP 9 BPDOWN 12 PULSE 106 OUT1 0 OUT2 1

========== CASE BLACKOUT ==========
// correct
BPUP 8 BPDOWN 11 PULSE 145 OUT1 0 OUT2 1

Answer 1

从我所看到的，不平等有问题：

  //Epistaxis and Blackout
   if (bpup >= 14 && bpdown > 9) {

对于bpup = 14也是如此，而你说它只对bpup＆gt;是真的14。

此外：

//Numbness
   if (bpup >= 15 && bpdown >= 9 && pulse <= 60) {

对于pulse = 60是正确的，而你说它必须对于脉冲＆lt; 60和对于bpdown = 9是正确的，而你说它只对bpdown＆gt;是真的9

输出有时是正确的和错误的
