為什么輸出不了i和j的值 構造方法里面的值不是已經賦值了嗎 為什么方法里不可以拿來用
public?class?Test{
int?i;
int?j;
public?Test(int?i,int?j){
}
public?void?show(){
System.out.println(i+j);
}
public?static?void?main(String[]?args){
Test?hello=new?Test(1,24);
hello.show();
}
}

?? public Test1(int i,int j){
???????? this.i = i;
???????? this.j = j;
??? }

剛剛學的，改構造方法里的int i,int j都是形參，要用指針。
