java Scanner输入问题

Question

我想一下子输入都个数；不想这么写，有没有简单点的方法

 Scanner in = new Scanner(System.in);
            int a = in.nextInt();
            Scanner in1 = new Scanner(System.in);
            int b = in.nextInt();
            Scanner in2 = new Scanner(System.in);
            int c = in.nextInt();

Answer 1

  Scanner in = new Scanner(System.in);  这样只要写一个就可以了，之后的只要有数字就可以一直nextInt
            int a = in.nextInt();
            Scanner in1 = new Scanner(System.in);
            int b = in.nextInt();
            Scanner in2 = new Scanner(System.in);
            int c = in.nextInt();

 Scanner in = new Scanner(System.in);
            int j=0;
            int[] a = new int[3];//输入几个，数组多大
            while(in.hasNext()){
                a[j]=in.nextInt();
                j++;
            }输入过程数字之间使用空格  最后结束是按Ctrl+Z
