entering integer in program

[MarkJ2]

New to Java here.....
I am writing a program which I would like the user to enter an integer. The integer will then be used for some other calculations. My code so far is:

//read in input, cast to char.
n = (char)System.in.read();

//assign 'n' to new String.
s = new String[n];

//using parseInt, change to an integer.
num = Integer.parseInt(s);

However when I run this, I get the error...incompatible type for = can't convert java.lang.String[] to java.lang.String.

Not really sure how to correct the problem.

Thanks for any help.

You need to wrap the InputStream in a BufferedReader and use read it a line at a time. Then you can use parseInt in the input.

You get the error because the line
s = new String[n];
tries to assign a String array of size n to s, and you can assign a String array to a String.
The String constructor you are trying to use takes a char array as a parameter.
But why don't you cast into a String in the first place?

I have to correct myself i have discovered a spelling mistake, it should say:
".....and you can't assign a String.....
