java user input code example

Example 1: how to take input in java

Scanner sc = new Scanner(System.in);  // Create a Scanner object
String userName = sc.nextLine();//read input string
int age = sc.nextInt(); //read input integer
long mobileNo = sc.nextLong(); //read input long
double cgpa = sc.nextDouble(); //read input double
System.out.println(userName);//output

Example 2: input java

Scanner in = new Scanner(System.in);
      System.out.print("Please enter hour 1: ");
      int hour1 = in.nextInt();
      System.out.print("Please enter hour 2: ");
      int hour2 = in.nextInt();
      System.out.print("Please enter minute 1: ");
      int min1 = in.nextInt();
      System.out.print("Please enter minute 2: ");
      int min2 = in.nextInt();

Example 3: java get input

Scanner sc = new Scanner(System.in);
String s = sc.next();
int n = sc.nextInt();
double d = sc.nextDouble();
float f = sc.nextFloat();

// more fast way
BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
String s = br.readLine(); // read line
int c = br.read();        // read single char

Example 4: how to use scanner class in java

// import Scanner
import java.util.Scanner;

// Initialize Scanner
Scanner input = new Scanner(System.in);

// Test program with Scanner
System.out.println("What is your name?");
String name = input.nextLine();

System.out.println("Hello," + name + " , it is nice to meet you!");

Example 5: how to get user input in java

import java.util.*;  
class UserInputDemo   
{  
public static void main(String[] args)  
{  
Scanner sc= new Scanner(System.in);    //System.in is a standard input stream  
System.out.print("Enter first number- ");  
int a= sc.nextInt();  
System.out.print("Enter second number- ");  
int b= sc.nextInt();  
System.out.print("Enter third number- ");  
int c= sc.nextInt();  
int d=a+b+c;  
System.out.println("Total= " +d);  
}  
}

Example 6: how to input in java

import java.util.Scanner;
...
  Scanner console = new Scanner(System.in);
  int num = console.nextInt();
  console.nextLine() // to take in the enter after the nextInt() 
  String str = console.nextLine();
