它说在Java中缺少2个分支中的1个

我有3节课。我试图通过名为“ main”的对象在main方法中设置一个变量,并通过编写super.getnumberofsets()来重用该值;在for循环中,但显示“缺少2个分支中的1个”。

 public static void main(){

//in the main method

//Main class maintain the private variables with their setters and getters.


 Main main = new Main();

 Sets sets = new Sets();


System.out.print("Enter how many sets you want to create: ");

newnumberofsets = in.nextInt();

main.set_numberofsets(newnumberofsets);

sets.setgroups();

sets.getgroups();

}

// in Sets class


protected void setgroups()

{

        //In this loop it says "1 of 2 branches missed".

        for(int x = 0; x<super.getnumberofsets();x++) { 
        main_zeroarray[x] = new Main0();
    }       
}

protected void getgroups() {
    count = 1;

    for(int x = 0 ;x < super.getnumberofsets();x++) {
        System.out.println(count + ". Set " + setnames[x]);
        count++;
    }

}

我希望super关键字将从对象main.set_newnumberofsets(newnumberofsets);读取相同的值。

1 个答案:

答案 0 :(得分:0)

最有可能的解释是,super.getnumberofsets()返回0,因此循环终止条件x < super.getnumberofsets()false,因此,循环增量x++从未执行,因此成为“遗漏的分支”。
