try放在for循环里面和外面的区别？先看看下面代码的区别：

public class Test {
        public void test1(){
            for (int count = 0; count < 6; count++) {
                try {
                    int x;
                    if (count == 3)
                        x = 1 / 0;
                    else{
                        x = count;
                        System.out.println(x);
                    }
    
                } catch(Exception e){
                    System.out.println("异常");
                }
            }
        }

结果：  
  
0  
1  
2  
异常  
4  
5

public void test2(){
            try {
                for (int count = 0; count < 6; count++) {
                    int x;
                    if (count == 3)
                        x = 1 / 0;
                    else{
                        x = count;
                        System.out.println(x);
                    }
                }   
            } catch (Exception e) {
                System.out.println("异常");
            }
           
        }
    
        public static void main(String[] args) throws Exception {
            Test te = new Test();
            te.test1();
            System.out.println("------------------------");
            te.test2();
        }
    }

结果

0  
1  
2  
异常  
  
  
\----------------------------------------------------------------------------------------------------------------  
  
  
总结：try放在for循环的里面所有的for循环都会执行，当遇到异常时，抛出异常继续执行；

放在外面，当遇到异常时，抛出异常，后面的循环就会终止，并不会执行。
