Java Exercises: Check whether three given lengths of three sides form a right triangle

Java Basic: Exercise-213 with Solution

Write a Java program to check whether three given lengths (integers) of three sides form a right triangle. Print "Yes" if the given sides form a right triangle otherwise print "No".

Input:

Integers separated by a single space. 1 ≤ length of the side ≤ 1,000

Sample Solution:

Java Code:

import java.util.Arrays;
import java.util.Comparator;
import java.util.Scanner; 
class Main {
    Scanner sc = new Scanner(System.in);
    public void run() {
		System.out.println("Input three integers(sides of a triangle)");
        int[] int_num = new int[]{
               sc.nextInt(),sc.nextInt(),sc.nextInt()
            };
            Arrays.sort(int_num);
			System.out.println("If the given sides form a right triangle?"); 
            ln((int_num[2]*int_num[2]==int_num[0]*int_num[0]+int_num[1]*int_num[1])?"Yes":"No");        
    } 
    public static void main(String[] args) {
        new Main().run();
    } 
    public static void pr(Object o) {
        System.out.print(o);
    } 
    public static void ln(Object o) {
        System.out.println(o);
    } 
    public static void ln() {
        System.out.println();
    }
}

Sample Output: 

Input three integers(sides of a triangle)
 6 9 12
If the given sides form a right triangle?
No

Java: Anagrams

Generates all anagrams of a string.

public static List<String> anagrams(String input) {
    if (input.length() <= 2) {
        return input.length() == 2
                ? Arrays.asList(input, input.substring(1) + input.substring(0, 1))
                : Collections.singletonList(input);
    }
    return IntStream.range(0, input.length())
            .mapToObj(i -> new SimpleEntry<>(i, input.substring(i, i + 1)))
            .flatMap(entry ->
                    anagrams(input.substring(0, entry.getKey()) + input.substring(entry.getKey() + 1))
                            .stream()
                            .map(s -> entry.getValue() + s))
            .collect(Collectors.toList());
}
