Question

EXERCISES: if & if...else STATEMENTS: Name Examples of if and if-else statements: Write an if statement that multiplies payRate by 1.5 iſ hours is greater than 40. Write variable declarations for the variables payRate and hours first. Hint: Look for keyword if first, your boolean comes after the keyword [. This translates into Java as: double hours, payRate; if (hours > 40) { //{-} are optional here but I recommend that you them payRate = payRate 1.5; pay Rato pay Rata Write an if statement sets the variable fees to 50.00 and adds fees to the variable totalFees if the Boolean variable maximum is true. Write variable declarations for the variables fees, maxium and totalFees first This translates into Java as: boolean maximum: double fees, totalFees: if (maximum) { /the same as if (maximum fees = 50,00; totalFees = totalFees + fees; } /{} are required here

Answer 1

Answer: Hey dear student finds the solution of your query if you have any doubt feel free to ask. Thanks!!

1- Java Code

int num,num1,num2;
if(num>100)
{
num1 = 20;
num2 = 40;
}

2- Java Program TimeCalculator

import java.io.*;
import java.util.Scanner; //import packages
class TimeCalculator
{
public static void main(String []args)
{
int seconds,leftover = 0,minutes = 0; //variable declarations
Scanner sc = new Scanner(System.in); //Scanner object
System.out.println("enter number of seconds: ");
seconds = sc.nextInt(); //takes input for seconds from user
if(seconds>=60) //check if seconds greater than or equalto 60
{
minutes = seconds/60; //to get minutes
leftover =    seconds%60; //to get seconds
}
System.out.println("Minutes: "+minutes); //print minutes
System.out.println("Leftover seconds: "+leftover); //print leftover
}
}

L UULEPI ILI LOILOVE enter number of seconds: 80 Minutes: 1 Leftover seconds: 20 ... Program finished with exit code A

3- Java Code

int varX,varY;
if(varY>150)
{
varX= 5;
}
else
{
varX = 10;
}

4- Java code

int num1,num2,num3;
if(num1<10)
{
num2 = 0;
num3 = 1;
}
else
{
num2 = -99;
num3 = 0;
}

5- Java program

import java.io.*;
import java.util.Scanner;
class Main
{
public static void main(String []args)
{
int length1,length2,width1,width2;
int area1,area2;
area1 = length1*width1;
area2 = length2*width2;
if(area1>area2)
{
System.out.println("Rectangle1 is greater");
}
else
{
System.out.println("Rectangle2 is greater");
}
}
}

Enter the lengthl: Enter the widthl: Enter the length2: Enter the width2: Rectangle2 is greater
