Thread: Help me with my code (im learning Java)

make a new string that takes the value of the scanner

You did it in post #20

	String uinputvar = uinput.nextLine();

What happens when you compile and execute the code?

Look at the statements in the program and think about what the computer will do as each statement is executed.
Make a list of the steps you want the program to do. Make each step as simple as possible, like you were explaining to a child what the program is to do.

Please write the steps as descriptions of what is to be done, not as comments in the program.

For example: Instructions on How to walk across the floor
Begin loop
Shift weight to left foot
Raise right foot
move right foot forward
put right foot on the floor
shift weight to right foot
lift left foot
move left foot forward
put left foot on floor
Are we close to the wall?
No, go to start of loop
Yes exit loop

my cursor says its loading... then nothing happens

Is the program waiting for you to enter some data?

1. Wait for the user input from the scanner
2. If the user input is the word "Sammy" then say "Hello Sammy"
3. If the user input is something else than sammy, say "Sorry, but you are not Sammy."

Where do you ask the user to enter his name?
Where do you save what the user entered?

Please work on one problem at a time. Make the list of what the program is supposed to do and then write the code to do that. Later change the code to use a different class and method.

Where is the user's input saved in step 1?

What is the java statement for comparing two Strings: the user's input and "Sammy"?

Use an assignment statement to save the value returned by a method:

aVar = someMethod(); // save value returned by someMethod() in aVar

What class and method are you using to read the input from the user?
Change the code I posted to use:
the variable in your code that is to hold the user's input
and the method that you are using to read the user's input.

Define a String variable
Assign that variable the value returned by the method that has read the user's input.

What method are you using to read the user's input?

Use an assignment statement:

theVar = aMethodThatReturnsValue();

What variable is to receive the value?
What method is called to get the user's input?

Perhaps you should consider dropping the course. Are you expecting someone to write every program that you are assigned? You need to learn how to do it. Otherwise why take the course.

You are having problems with some very basic concepts:

What is a variable
How to assign a value to a variable
How to call a method
How to assign the value that the method returns to a variable.

You will be using these concepts over and over and over when writing programs.
