COMP-274 Week 1 Programming Assignment Do the following two programs: 1. Write a Java application that inputs three integers from the user and displays the sum, average, product, smallest and largest of the numbers. Use a Scanner object to get the input from the user. Use System.out to output the results. The average should be a floating point result, and should be displayed with 2 digits after the decimal point. 2. Write a Java application which tests the random number generation abilities of Java. Random number generation is explained below.Your application should simulate rolling a pair of dice some number of times. Use a JOptionPane to ask the user how many times the dice should be rolled. Each dice roll can be a value between 1 and 6, so rolling 2 dice will result in values between 2 and 12. You need to generate a random number between 1 and 6 to simulate rolling each dice. Keep track of the result of each roll using an array that is indexed by the sum of the roll of the two dice. Output your result in a table which shows each value (ie. 2

Explanation / Answer

// Make simple calculations on three integers. //Programmer note: You can also use the Scanner Object instead of the traditional GUI components. import javax.swing.JOptionPane; public class Calculate2 { public static void main( String[] args ) { String firstNumber, secondNumber, thirdNumber; String result; int number1, number2, number3; int sum, largest, smallest, product, average; //read first number from user as string firstNumber = JOptionPane.showInputDialog( “Enter first number: ” ); //read second number from user as a string secondNumber = JOptionPane.showInputDialog( “Enter second number: ” ); //read third number from user as a string thirdNumber = JOptionPane.showInputDialog( “Enter third number: ” ); //convert numbers from type String to type int number1 = Integer.parseInt( firstNumber ); number2 = Integer.parseInt( secondNumber ); number3 = Integer.parseInt( thirdNumber ); //initialize largest and smallest largest = number1; smallest = number2; //determine correct values if ( number2 >= number1 ) { largest = number2; smallest = number1; } if ( number3 > largest ) largest = number3; if ( number3
