System.out.print(“Protect environments from e-wastes”);
System.out.print(“Java is meant for Object Oriented Programming Design”);

However, you can also use the println() method to print numbers. Unlike text, double
quotes are not needed for numbers. For example, you can demonstrate the println() Chapter Five: Object oriented programming with Java

method for numbers as follows:
System.out.println(116);
System.out.println(985); and
System.out.println(5 + 6);

(c) Java comments
The java comments are statements that are not executed by the compiler and
interpreter. The comments can be used to provide information or explanation about
the variable, method, class or any statement. It can also be used to hide program
code for specific time. There are 3 types of comments in java, namely: single line
comment, multi line comment, and documentation comment
(i) Java single line comment
A single line comment is used to comment only one line. A single-line comment
begins with a
// and ends at the end of the line. For example “//This is a comment”
(ii) Java multi line comment
A multi-line comment in Java starts with /* and ends with */. Anything between
these symbols is ignored by the compiler. This type of comment can span several
lines. For example, /* This is a comment that is multi line. The comments may
have several lines*/
(iii) Java documentation comment
This type of comment, as shown in Table 5.4, is used to produce an HTML file
that documents our program. The documentation comment begins with a /**
and ends with a */.

Table 5.4: Documentaion comment
Syntax Example
/**Starting of the comments /**
* The first comment These
*Second comment and so on… Are
* important
* comments to
* use in Java
*Comments ends like this */ */
