Question
Arrange the below code in correct order :import java.util.Scanner;public static void main(String args[]) {Scanner sc=new Scanner(System.in);public class Main{int num1 = sc.nextInt();System.out.println("The value is "+num1);}}
Solution
Here is the correct order of the Java code:
import java.util.Scanner;
public class Main{
public static void main(String args[]) {
Scanner sc=new Scanner(System.in);
int num1 = sc.nextInt();
System.out.println("The value is "+num1);
}
}
Explanation:
-
First, we import the necessary libraries, in this case,
java.util.Scannerwhich is used for getting user input. -
Then, we define the class. In Java, every application must contain a main class that wraps up all the code. Here, the class is named
Main. -
Inside the class, we define the
mainmethod. This is the entry point for any Java application. The Java Virtual Machine (JVM) calls themainmethod when the program starts. -
Inside the
mainmethod, we create a newScannerobject that reads the input from the user. -
We declare an integer
num1and assign it the value of the next integer input from the user. -
Finally, we print out the value of
num1usingSystem.out.println.
