Java Comments
Java Comments are used for better understanding & good explanation of codes and to prevent unnecessary code from executing.
Single-line Comments
In Java, single-line comments start with two forward slashes (//).
Any text that starts with // and the end of the line is not considered a code line by Java and will not be executed.
Example: Use a single-line comment before a line of code.
// write the “Hello World” program.
public class Main{
public static void main(String[] args){
System.out.print("Hello World ");
}
}
Example: Use a single-line comment at the end of a line of code.
public class Main{
public static void main(String[] args){
System.out.print("Hello World "); // write the “Hello World” program.
}
}
Java Multi-line Comments
In Java, if we have to write more than one line of comments, then use Multi-line comments that start with /* and end with */.
Example: Use a multi-line comment (like a block of comments) to explain the code.
/* write the “Hello World” program
In this Java file named Main.java.
*/
public class Main{
public static void main(String[] args){
System.out.print("Hello World ");
}
}
