幫我看一下為什么three前面為什么不能加int可以嗎
public class HelloWorld{
? ? public static void main(String[] args) {
? ? int one = 10 ;
? ? ? ? int two = 20 ;
? ? ? ? int three = 0 ;
? ? ? ?int three = one+two;
? ? ? ? ?System.out.println("three = one +two ==>"+three);
? ? ? ? int three += one;
? ? ? ? ? System.out.println("three += one ==>"+three);
? ? ? ? ?int three *= one;
? ? ? ? ? ?System.out.println("three = *= one ==>"+three);
? ? ? ? ? ?int three /= one;
? ? ? ? ? ? System.out.println("three /= one ==>"+three);
? ? ? ? ? ? int three %=one;
? ? ? ? ? ? ?System.out.println("three %=one ==>"+three);
? ? ? ??
