Left! Right! One should also use the string literals "\n" and "\r", respectively, for correct interpretation of the characters "\u000a" and "\u000d" in the source code. White Spaces A white space is a sequence of spaces, tabs, form feeds, and line terminator characters in a Java source file. Line terminators can be newline, carriage return, or carriage return-newline sequence. A Java program is a free-format sequence of characters that is tokenized by the compiler, that is, broken into a stream of tokens for further analysis.

This is reflected in the definition of the CharStack class, which contains an instance variable for each of these parts. In contrast to the constituent objects whose references are stored in fields, the values of primitive data types are stored in the fields of the composite object. 7, showing that each object of the CharStack class will have one array object of char associated with it. 7. 8 Tenets of Java • Code in Java must be encapsulated in classes. • There are two kinds of values in Java: object references and atomic values of primitive types.
