真布爾while語句不退出循環中嵌套IFS

Question

當我設置while1一個迴路，其中while1的值是真實的假=內部和循環條件是當（while1）它應該退出循環。不過，在嵌套if語句中，它似乎沒有這樣做。

package javanotes; 
import java.util.Scanner; 

public class EggsCount { 

    static Scanner var1 = new Scanner(System.in); 

    public static void main (String[] args){  

     int eggNumber; 
     int eggsGross; 
     int eggsDozen; 
     int eggsSingle; 
     int eggsGrossRemainder; 
     int eggsDozenRemainder; 
     boolean while1 = true; 
     boolean while2 = true; 

     System.out.println("How many eggs do you have?"); 
     eggNumber = var1.nextInt(); 

     while (while1){ 
      if (eggNumber > 144){ 
       eggsGross = eggNumber/144; 
       eggsGrossRemainder = eggNumber % 144; 

       if(eggsGrossRemainder > 12) { 
        eggsDozen = eggsGrossRemainder/12; 
        eggsDozenRemainder = eggsGrossRemainder % 12; 
        if (eggsDozenRemainder > 0){ 
         eggsSingle = eggsDozenRemainder; 
         System.out.println("You have " + eggsGross + " gross amount of eggs, " + eggsDozen + " dozens mounts of eggs, and " 
           + eggsSingle + " remainder eggs."); 
         while1 = false; 
        } 
        System.out.println("You have " + eggsGross + " gross amount of eggs and " + eggsDozen + " dozens mounts of eggs."); 
        while1 = false; 
       } 
       System.out.println("You have " + eggsGross + " gross amounts of eggs."); 
       while1 = false; 
      } 
      else if(eggNumber <= 144 && eggNumber >= 12){ 
       eggsDozen = eggNumber/12; 
       eggsDozenRemainder = eggNumber % 12; 
       if (eggsDozenRemainder > 0){ 
        eggsSingle = eggsDozenRemainder; 
        System.out.println("You have " + eggsDozen + " dozen eggs and " + eggsSingle + " remainders."); 
        while1 = false; 
       } 
       System.out.println("You have " + eggsDozen + " dozen eggs."); 
       while1 = false; 
      } 
      else if (eggNumber > 0 && eggNumber < 12){ 
       eggsSingle = eggNumber; 
       System.out.println("You have no Gross amounts or Dozen amounts, only " + eggsSingle + " singles."); 
       while1 = false; 
      } 
      else{ 
       System.out.println("C'mon now... let's put a normal value in:"); 
      } 
     } 
    } 
}

轉動布爾假，意味着迴路將不會完成另外反過來，然而，將會沿其路徑繼續，即「47」雞蛋是> 12且小於「144」，eggsDozenRemainder是> 0，因此如果塊將會運行，但是如果判定不是相互排斥的話，那麼後面的塊也是如此，嘗試If（）{} else {}
