+public class Input {

+		// In JAVA we have a Scanner class that allows us to take input and this is the
+		// statement how we call it in our main class
+		// So lets say i need you age , your name and your grades in 'double'
+		int age = in.nextInt();// to take age from user we call .nextInt() function from our imported Scanner
+								// class
+		double grade = in.nextDouble();
+		// And this function is used to take double input from user
+		// String name = in.next();now for string we have two functions the first
+		// function stops taking input as soon as you hit space
+		String name = in.nextLine();// but this function takes space between two words as well thats why i used this
+		// in my code
+		if (name.isEmpty()) {// Bonus information if you take input like thid String after int java will Show
+								// you error hit is almost written in this code try to find out why XD you rhome
+								// work. so to remove that error we need to check that if from the first input
+								// statement name does not take any value we need to store again a value in it
+			name = in.nextLine();// and finally your code works
+		}
+		System.out.println("Your Age :" + age);
+		System.out.println("Your name :" + name);
