Explore working with strings in Java, including the use of mutable strings through the StringBuilder class. In this course, you will discover the nature and use of strings and primitive data types, in Java. Observe how to compare and sequence strings, through equality tests and lexicography. Discover mutable strings, the advantages of string builder, and how to concatenate strings. Next, split a string via a regular expression, and learn how to split a paragraph of text into words in a string and iterate over individual words.Other topics include how to consider primitive data types, how to perform the standard modulus mathematical operation on an integer. Finally, you will use combined assignment operators to abbreviate common operations.
