how can i separate this code in two methods

method for time like this ----------------->( public static long getTestTime(starttime,endTime) {

and method for level1

JAVA

-------------------------------------------------------------------------------------------------------------------

public class JavaApplication108 {

/** * @param args the command line arguments */ public static void main(String[] args) { Scanner input = new Scanner(System.in);

int x, y, z;

int correctCount = 0; // Count the number of correct answers int count = 0; // Count the number of questions String output = ""; // output string is initially empty long starttime = System.currentTimeMillis();

while (count < 5) {

x = (int) (Math.random() * 10) + 10; y = (int) (Math.random() * 10) + 10; z = 0; int min = 0; int max = 4; // exclusive int num = (int) (Math.random() * (max - min) + min); char operator = ' ';

switch (num) { case 0: operator = '+'; z = x + y; break; case 1: operator = '-'; z = x - y;

break; case 2: operator = '*'; z = x * y;

break; case 3: operator = '/'; z = x / y;

break; default: operator = '?'; }

System.out.println(x + " " + operator + " " + y); System.out.println("....."); int val = input.nextInt(); if (z == val) { System.out.println("Correct"); correctCount++; } else { System.out.println("worng"); } count++; break; }

long endTime = System.currentTimeMillis(); long testTime = endTime - starttime;

System.out.println("Correct count is " + correctCount + " Test time is " + testTime / 1000 + " seconds " ); } }
