Break 和 Return的用法.

1. Break 和 Return 都可以跳離迴圈. 2. 但是Return會跳出函式而不執行接下來的程式碼.

 public class BreakAndReturnDemo {  
      public static void main(String[] args){  
           printWord();  
           printWordWithReturn();  
      }  
      public static void printWord(){  
           for(int i = 0 ; i < 10 ; i++){  
                System.out.println(i);  
                if(i == 5){  
                     break;  
                }  
           }  
           System.out.println("After break for loop");  
           System.out.println("====Seperate Line========");  
      }  
      public static void printWordWithReturn(){  
           for(int i = 0 ; i < 10 ; i++){  
                System.out.println(i);  
                if(i == 5){  
                     return;  
                }  
           }  
           System.out.println("This line won't be executed.");  
      }  
 }
