Java Program to Take Input From User - The Coding Shala

Home >> Java Programs >> Take User Inputs

 Hey there, welcome back to another post. In this post, we are going to learn how to take inputs from the user in Java.

Java Program to Take Input From User

Here, we are going to use the Scanner class to take user input. We will use the below methods:

  • For integer: nextInt()
  • For long: nextLong()
  • For float: nextFloat()
  • for double: nextDouble()
  • for String: next()
  • for complete line: nextLine()
Java Program: 

import java.util.Scanner;

/**

 */

public class Main {

    public static void main(String[] args) {
        // using Scanner class
        Scanner sc = new Scanner(System.in);

        // taking integer inputs
        // for integers use nextInt()
        // for long use nextLong()
        System.out.println("Enter integer");
        int num1 = sc.nextInt();
        System.out.println("Entered integer is: " + num1);

        // taking float/Double input
        // for float -> nextFloat()
        // for double -> nextDouble()
        System.out.println("Enter float");
        float num2 = sc.nextFloat();
        System.out.println("Entered float is: " + num2);

        // taking string input using next()
        System.out.println("Enter a string");
        String str = sc.next();
        System.out.println("Entered string is: " + str);

        // taking complete line as string input using nextLine()
        // it will move the cursor to the next line
        System.out.println("Enter a string with spaces in between");
      //  String str2 = sc.next(); -> this will take only first word
        sc.nextLine(); // this will move current cursor to the starting of next line
        String str2 = sc.nextLine();
        System.out.println("Entered string is: " + str2);
    }
}

Output: 

Enter integer
5
Entered integer is: 5
Enter float
3.5
Entered float is: 3.5
Enter a string
Akshay
Entered string is: Akshay
Enter a string with spaces in between
Hello Akshay, How are you?
Entered string is: Hello Akshay, How are you?

N-th Tribonacci Number Solution - The Coding Shala

Home >> Programming >> N-th Tribonacci Number  Hey there, welcome back to another post. In this post, we will learn how to solve the N-th Tribonacci Number problem and will implement its solution in Java. N-th Tribonacci Number Problem Statement The Tribonacci sequence Tn is defined as follows: T0 = 0, T1 = 1, T2 = 1, and Tn+3 = Tn + Tn+1 + Tn+2 for n >= 0. Given n, return the value of Tn.  Example 1:  Input: n = 4 Output: 4 Explanation: T_3 = 0 + 1 + 1 = 2 T_4 = 1 + 1 + 2 = 4 N-th Tribonacci Number Java Solution using Bottom-Up DP This problem is similar to the Fibonacci series. We can solve it using the Bottom-Up approach of dynamic programming. Time Complexity: O(n) Space Complexity: O(n) The space complexity can be reduced to O(1) by using variables to store the previous three values instead of using an array. Java Program:  class Solution { public int tribonacci( int n) { if (n == 0) return 0; ...

Java Program to Convert Binary to Decimal - The Coding Shala

Home >> Java Programs >> Convert Binary to Decimal  Hey there, welcome back to another post. In this post, we will learn how to convert Binary to Decimal in Java. Java Program to Convert Binary to Decimal You have given a binary number, convert it to a decimal number. Example:  Input: 101 Output: 5 Input: 111 Output: 7 Binary to Decimal Conversion in Java Approach We will the below formula to convert binary to decimal: decimal number = (2^0) * (rightmost digit) + (2^1) * (second rightmost digit) + ...  for example:  binary number = 110 decimal number = 2^0 * 0 + 2^1 * 1 + 2^2 * 1 = 1 * 0 + 2 * 1 + 4 * 1 = 0 + 2 + 4 = 6 Java Program:  import java.util.Scanner; /** * https://www.thecodingshala.com/ */ public class Main { public static void printDecimal( int num) { int decimal = 0; int twos = 1; // 2^0 = 1 initial value while (num > 0) { ...

LeetCode - Shuffle the Array Solution - The Coding Shala

Home >> LeetCode >> Shuffle the Array  In this post, we will learn how to solve LeetCode's Shuffle the Array problem and will implement its solution in Java. Shuffle the Array Given the array nums consisting of 2n elements in the form [x1,x2,...,xn,y1,y2,...,yn]. Return the array in the form [x1,y1,x2,y2,...,xn,yn]. Example 1: Input: nums = [2,5,1,3,4,7], n = 3 Output: [2,3,5,4,1,7]  Explanation: Since x1=2, x2=5, x3=1, y1=3, y2=4, y3=7 then the answer is [2,3,5,4,1,7]. Example 2: Input: nums = [1,2,3,4,4,3,2,1], n = 4 Output: [1,4,2,3,3,2,4,1] Practice this problem on LeetCode: Click Here. Shuffle the Array Java Solution Approach 1: Using a new Array.

Java Program to Find GCD or HCF of Two Numbers - The Coding Shala

Home >> Java Programs >> Find GCD of Two Numbers  Hey there, welcome back to another post. In this post, we will learn how to find GCD or HCF of Two Numbers in Java. Java Program to Find GCD or HCF of Two Numbers The GCD (Greatest Common Divisor) or HCF (Highest Common Factor) of two numbers is the largest number that divides both of them. For example:  Number1: 6 (2 * 3) Number2: 9 (3 * 3) GCD or HCF of 6 and 9 is: 3 Find GCD of Two Numbers in Java using for Loop As we already know, GCD is the largest number that divides both numbers. We can start a for loop from 1 (because 1 divides all the numbers) to both numbers and if it divides both numbers then update GCD. Java Program:  import java.util.Scanner; /** * https://www.thecodingshala.com/ */ public class Main { public static void findGCD( int num1, int num2) { int gcd = 1; if (num1 == 0) { gcd = num2; } if (num2 == 0) { ...
