The given task is to take an integer as input from the user and print that integer in Java language.
In the below program, the syntax and procedures to take the integer as input from the user are shown in Java language.
Steps for Input
- The user enters an integer value when asked.
- This value is taken from the user with the help of nextInt() method of Scanner Class. The nextInt() method, in Java, reads the next integer value from the console into the specified variable.
Syntax of Scanner Class
variableOfIntType = ScannerObject.nextInt();
where variableOfIntType is the variable in which the input value is to be stored.
And ScannerObject is the beforehand created object of the Scanner class.
Steps for Output
- This entered value is now stored in the variableOfIntType.
- Now to print this value, System.out.println() or System.out.print() method is used. The System.out.println() method, in Java, prints the value passed as the parameter to it, on the console screen and the changes the cursor to the next line on the console. Whereas System.out.print() method, in Java, prints the value passed as the parameter to it, on the console screen and the cursor remains on the next character of the last printed character on the console.
Syntax of println
System.out.println(variableOfXType);
Hence, the integer value is successfully read and printed.
Program Read and Print an Integer value in Java
Below is the implementation of the above method:
Java
// Java program to take an integer// as input and print itimport java.io.*;import java.util.Scanner;// Driver Classclass GFG { // main function public static void main(String[] args) { // Declare the variables int num; // Input the integer System.out.println("Enter the integer: "); // Create Scanner object Scanner s = new Scanner(System.in); // Read the next integer from the screen num = s.nextInt(); // Display the integer System.out.println("Entered integer is: " + num); }} |
Input
Enter the integer: 10
Output
Entered integer is: 10
