2、下面程序段的执行结果是【3】__12345____________

public
class MyClass {
    int
a[] = { 1, 2, 3, 4,5 };
    void out()

    {   for (int j = 0; j <
a.length; j++)

           System.out.print(a[j] +
""); 
    }
    public
static void main(String[] args) {
       MyClass my = new MyClass();

      　my.out(); 
    }
}

源代码

public class test_two {

    int a[] = { 1, 2, 3, 4, 5 };
void out() 
{   
for (int j = 0; j < a.length; j++) 
System.out.print(a[j] + "");  
} 
public static void main(String[] args) {
  test_two my = new test_two();
  my.out();
}

}
