switchtest.java

java学习的一些运行实例！我觉得瞒有用

class switchtest { 
 public static void main (String args[]) throws java.io.IOException 
 {  char c; 
    int numberOfDigits=0, numberOfSpaces=0, numberOfOthers=0; 
    while((c=(char)System.in.read())!='\n') {   
      switch(c) {   
        case '0' : 
        case '1' : 
        case '2' : 
        case '3' : 
        case '4' : 
        case '5' : 
        case '6' : 
        case '7' : 
        case '8' :               
        case '9' : numberOfDigits++; break; 
        case ' ' : numberOfSpaces++; break; 
        default: numberOfOthers++; break;     
       }     
    }   
    System.out.println("Number of digits="
                 +numberOfDigits+" "); 
    System.out.println("Number of spaces="
                +numberOfSpaces+" "); 
    System.out.println("Number of others="
                +numberOfOthers+" "); 
   } 
}
