Constantly ask the user for a number. End the program when zero is entered. Write a code in Java that results like test case 1

Instructions from your teacher: Write a program that asks the user to enter a character. Then pass the character to the following methods.   changeCase() – if the character is lower case then change it to upper case and if the character is in upper case then change it to lower case.   Example output is given below: Enter a character  a a is equivalent to A   Note: Java represents character using Unicode encoding and ‘A’ to ‘Z’ is represented by numbers 65 to 90 and ‘a’ to ‘z’ is represented by numbers 97 to 122. So to convert ‘A’ to ‘a’ you need to add (97-65) to A and then cast it to Character type since the addition will change its type to integer. You can use the following code to read a character from console. When you call charAt(i) method for any String it returns the character at index i. The index of first character is 0, the index of second character is 1 and so on. Scanner input = new Scanner(System.in); char ch =input.next().charAt(0);   If you…

Hey all, Need some help on best way to go about this question. All coding is done in Java. I am using the IntelliJ Idea, as the base for the code if it helps. Question is as follows: A  car’s  miles-per-gallon (MPG)  can  be calculated  with the following  formula: MPG =  Miles  driven /  Gallons  of  gas  used Write a java  program  that  prompts  the user  for  the number  of  miles  driven and the gallons  of  gas  used.  It  should  calculate the car’s  miles-per-gallon  and display  the  result on the screen.
