How do you reintroduce the keyboard and reduce the Java code?

[kalyn]

Method numCheckEquals accepts 4 whole numbers with a,b,c,d. In the cycle for me, I'm going to the method. numCheckEquals 4 digits from the console, and I write every time. sc.nextInt(); What if the program requires 100 digits, imagine what a huge code is gonna be like, how to reduce it. sc.nextInt();

public class Main {
public static void main(String[] args) {
Scanner sc = new Scanner(System.in);

for (int i = 0; i <= 4; i++) {
    System.out.println(Solution.checkNumEquals(sc.nextInt(), sc.nextInt(), sc.nextInt(), sc.nextInt()));
}

}

Accept values in the endless cycle. ♪ ♪

  Scanner console = new Scanner(System.in);
            while (true) {
                int nextInt = console.nextInt();
            System.out.println(nextInt);
            if (nextInt == -1) // условие выхода
                break;

Also available Varargs - these are the variable length arguments that allow us to create methods with an arbitrary number of arguments.

public class Solution {

static void varArgs(int... nums) {

for (int num : nums) {

System.out.print(num);

}

System.out.println();

}

public static void main(String[] args) {

    varArgs(1,2,3,4,5,6,7,8,9);
    varArgs(1,2,3,4);
    varArgs(5,6,7,8,9);

}

}

Or read the method hasNext
