Summary: Unlike C/C++, Java comes with naming conventions to increase the readability of code. This "Java Naming Conventions Readability" explains how to do it.
After knowing the rules of identifiers, it is the time to know the another grammar of Java known as "conventions". Conventions increase the readability of the program. Conventions are applied to identifiers. An identifier, in Java, may denote a class name, a variable name or a method name. Java follows "Hungarian notation" in naming conventions. Conventions are very simple to remember.
The starting letter of each word, in a class name, should be of uppercase.
The starting letter of the first word should be of lowercase and the starting letter of all the remaining words should be of uppercase.
Convention for method is simply that of variable only but followed by parenthesis.
