Explore the use of variables and operations using strings and numeric types in Java. During this course, you will declare, initialize, and concatenate Java string variables. See how to use the indexOf and substring functions. Declare and initialize Integer and floating-point variables. Learn to modify numeric variables via basic Java mathematical operators. Explore operator precedence rules. Set precedence through parentheses in a Java expression. Assign and concatenate integers and strings. Finally, as a review exercise, you will concatenate various Java variable types to create strings.
