======================= Swap.java ====================================
CODE:
import java.util.Scanner; // Import the Scanner class public class Swap { static int First_Number; //for store the first integer value from the user static int Second_Number; //for store the second integer value from the user public static void main(String args[]) { Scanner myObj = new Scanner(System.in); // Create a Scanner object System.out.print("Enter First Integer value:-"); First_Number = myObj.nextInt(); // Read user input System.out.print("Enter Second Integer value:-"); Second_Number = myObj.nextInt(); // Read user input System.out.println("\n Before swap"); System.out.println("First Integer Value is: " + First_Number); System.out.println("Second Integer Value is: " + Second_Number); //Function call swap(First_Number,Second_Number); } //Function Declaration public static void swap(int first,int second) { //Changing the variable Values First_Number = second; Second_Number = first; //Printing the value System.out.println("\n After swap"); System.out.println("First Integer Value is: " + First_Number); System.out.println("Second Integer Value is: " + Second_Number); } }
OUTPUT:
============================Main.java ===============================
CODE:
public class Main { static int First_Number; static int Second_Number; public static void main(String args[]) { First_Number = 10; Second_Number = 20; System.out.println("\n Before swap"); System.out.println("First Integer Value is: " + First_Number); System.out.println("Second Integer Value is: " + Second_Number); swap(First_Number,Second_Number); First_Number = 15; Second_Number = 25; System.out.println("\n Before swap"); System.out.println("First Integer Value is: " + First_Number); System.out.println("Second Integer Value is: " + Second_Number); swap(First_Number,Second_Number); } public static void swap(int first,int second) { First_Number = second; Second_Number = first; System.out.println(" \n After swap"); System.out.println("First Integer Value is: " + First_Number); System.out.println("Second Integer Value is: " + Second_Number); } }

Write a Java program that allows the following: 1.Create an array list of 20 integers. The 20 integers are generated randomly with possible values from 0 to 10. 2.Print the content of the array list. 3.Find how many of these values are multiple of 3. Show a screenshot of the output with your name and Id in the first line (if there is no screenshot of the output, the student shall get a zero mark for this question). Program typical...
Write a recursive method in java to find GCD of two integers using Euclid's method. Integers can be positive or negative. public class Recursion { public static void main(String[] args) { Recursion r = new Recursion(); System.out.println(“The GCD of 24 and 54 is “+r.findGCD(24,54)); //6 } public int findGCD(int num1, int num2){ return -1; } }
JAVA HELP! Question: Write a Java console application that investigates how well Java handles large integers. Write two loops that iterate from 0 through 35. Before each loop, set an integer variable (IV) to 1. Within each loop, print the loop count and the value of IV formatted in two columns. Within the first loop, multiply IV by 2. Within the second loop, multiply IV by the appropriate StrictMath method. The second loop will not complete since there will eventually...
Java generics Write a program that calls a method to multiply two integers and return the integer result. Modify the program to make the method generic, calling it with two generic data types and then returning the result in the same type which also has to be generic. Call the method two times, once with an integer and once with a double in your main program and display the results

Write a program that will accept two integers on command line, use the swap subprogram to swap them, and then print the two numbers out. For example, I enter a.out 10 15 and the output that would print is 15 10. Please note that if exactly two numbers are not provided on command line, your program should display an error message and end with no further action. The programming language is C Compiler.
