data is less than 0 then output should display negative number, otherwise if you input data

that is greater than equal to 0 then output should display positive number. Save the file as

NegativePositive.java.


public class NegativePositve

{

Public static void main(String[] args)

{

int number = -4;

if (number < 0)

System.out.println(negative number);

else if (number >= 0)

System.out.println(Positive number);

}

}

What if the output of the program?

negative number

Write a Java application that asks a user to enter an IQ score. If the score is a number lees than

0 or greater than 200, issue an error message; otherwise, issue an Above average for scores

over 100, Average for score at 100 or Below average for scores under 100. Save the file as

IQ.java.


public class IQ

{


{

int IQ = 120;

if (IQ < 0 || IQ > 200)

System.out.println(Above average);

else if (IQ == 100)

System.out.println(Average);

else

System.out.println(Below average);

}

}


Below average


Write an application that prompts user for two integers and then prompts the user to enter and

option. If the choice is 1, add the two integers, If it is 2, subtract the second integer from the

first. If it is 3, multiply the integers. Display the results of the arithmetic. Save the file as

Calculate.java.



public class Calculate

{


{

int Integer1 = 4, Integer2 = 9;

String choice = JOptionPane.showInputDialog(null, ENTER YOUR CHOICE 1-3, INPUT,


JOptionPane.showMesageDialog(null, YOU CHOSED + choice, OUTPUT,


int intValue = Integer.parseInt(choice);

if (intValue == 1)

JOptionPane.showMessageDialog(null, OUTPUT = + (Integer1 + Integer2), OUTPUT,


else if (intValue == 2)

JOptionPane.showMessageDialog(null, OUTPUT = + (Integer1 Integer2), OUTPUT,



JOptionPane.showMessageDialog(null, OUTPUT = + (Integer1 * Integer2), OUTPUT,

JOptionPane.INFORMATION_MESSAGE); }

}


Create a program that will determine if the student score is passed of failed, if the score

is greater that equal to 75 the program should display Passed, buy if the score is less than 75,

public class StudentGrade

{


{

String Grade = JOptionPane.showInputDialog(null, ENTER YOUR GRADE, INPUT,


JOptionPane.showMessageDialog(null, YOUR GRADE: + Grade, OUTPUT,


Int intValue = Integer.parseInt(Grade);

If (intValue >= 75)

JOptionPane.showMessageDialog(null, YOU PASSED, OUTPUT,


else

JOptionPane.showMessageDialog(null, YOU FAILED, OUTPUT,


}

}


Write a program for furniture company; the program determines the price of a table. Ask the

mahogany table cost Php500. If the user enters invalid wood code set the price to 0. Save the

file as Furniture.java.



public class Furniture {


String Wood = JOptionPane.showInputDialog(null, Enter wood code from 1-3, INPUT,


JOptionPane.showMessageDialog(null, YOU CHOSED + Wood, OUTPUT,


int intValue = Integer.parseInt(Wood);

int Table1 = 100, Table2 = 250, Table3 = 500;

if (intValue == 1)

JOptionPane.showMessageDialog(null, Pine table cost + Php + Table1, OUTPUT,



JOptionPane.showMessageDialog(null., Oak table cost + Php + Table2, OUTPUT,



JOptionPane.showMessageDialog(null, Mahogany table cost + Php + Table3, OUTPUT,


}

}
