I'm extremely new to Java, and I had a bit of an attempt at making something that you could call lotto. I've still got a lot more to go on it, but things are becoming tedious, and I am sure there is a simpler way to do what I am doing.  How can this code be changed to have less repetitive code/optimized?import java.util.Random;import java.util.Scanner;public class Lotto {    //Pick 6 numbers from 1 to 100    //If all of your numbers gets called out, you win    public static void wait (int n) {        long t0,t1;        t0=System.currentTimeMillis();        do{            t1=System.currentTimeMillis();        }        while (t1-t0<1000);    }    public static void main(String[] args) {        Random rand = new Random();        Scanner numScan1 = new Scanner(System.in);        Scanner numScan2 = new Scanner(System.in);        Scanner numScan3 = new Scanner(System.in);        Scanner numScan4 = new Scanner(System.in);        Scanner numScan5 = new Scanner(System.in);        Scanner numScan6 = new Scanner(System.in);        boolean num1Cor = false;        boolean num2Cor = false;        boolean num3Cor = false;        boolean num4Cor = false;        boolean num5Cor = false;        boolean num6Cor = false;        System.out.print(Pick 6 numbers from 0 to 25. Pick your first number: );        int num1 = numScan1.nextInt();        System.out.println();        System.out.print(Pick your second number: );        int num2 = numScan2.nextInt();        System.out.println();        System.out.print(Pick your third number: );        int num3 = numScan3.nextInt();        System.out.println();        System.out.print(Pick your fourth number: );        int num4 = numScan4.nextInt();        System.out.println();        System.out.print(Pick your fifth number: );        int num5 = numScan5.nextInt();        System.out.println();        System.out.print(Pick your final number: );        int num6 = numScan6.nextInt();        System.out.println(Numbers will now start to be drawn, if all of your numbers are called, you win.);        while (true) {            int random = rand.nextInt(25);            System.out.println(Number  + random + .);            if (random == num1) {                num1Cor = true;                System.out.println(Your number,  + num1 + , has been called.);            }            else if (random == num2) {                num2Cor = true;                System.out.println(Your number,  + num2 + , has been called.);            }            else if (random == num3) {                num3Cor = true;                System.out.println(Your number,  + num3 + , has been called.);            }            else if (random == num4) {                num4Cor = true;                System.out.println(Your number,  + num4 + , has been called.);            }            else if (random == num5) {                num5Cor = true;                System.out.println(Your number,  + num5 + , has been called.);            }            else if (random == num6) {                num6Cor = true;                System.out.println(Your number,  + num6 + , has been called.);            }            if (num1Cor == true && num2Cor == true && num3Cor == true && num4Cor == true && num5Cor == true && num6Cor == true) {                System.out.println(You win!!);                break;            }            wait(100);        }    }}
