# if statements

Exercise 1 Create a Java class named IfDemo that has a “main” similar to class FirstProgram in Lab 1. 1. Write a program that will print whether a number is odd or even. A number is even you divide it by 2 and the remainder is 0. Use an if-else statement and the modulus (%) operator to create output like the following: Input a number: 35 The number 35 is odd. And, if the program is run again: Input a number: 76 The number 76 is even. Copy the source code and the output into a word processing document called Lab3. Exercise 2 A number is positive if it is greater than 0, negative if it is less than 0, and zero if it’s value is 0. Comment out the code from exercise 1 and add code to create output like the following: Input a number: 35 The number 35 is positive. And, if the program is run again: Input a number: -53 The number -53 is negative. And, if the program is run again: Input a number: 0 The number 0 is zero. Copy the source code and the output into the word processing document. Exercise 3 A number is a teen if its value is between 13 and 19 inclusively. Comment out the code from exercise 2 and add code to create output like the following: Input a number: 35 The number 35 is not a teen. And, if the program is run again: Input a number: 16 The number 16 is a teen. Copy the source code and the output into the word processing document and submit the file. Attachments
