Java as a programming language involves a set of rules defining its syntax and structure. One of these rules is the requirement of semicolons for the end of each statement.
What Does a Semicolon Mean in Java?
A semicolon is a punctuation mark which indicates the end of a statement in Java. Java programs are made up of instructions in form of statements and each must be written with the correct syntax and terminated by a semicolon. The semicolon signals the compiler that the statement has been concluded and that it should then continue to evaluate the program.
Why Is it Necessary to End Java Statements with a Semicolon?
The semicolon is necessary to denote the end of a statement and enforce the syntax for the language. It helps the compiler differentiate between statement ending and other characters. Thus, ending each statement with a semicolon enables the compiler to break up the code into individual instructions and understand precisely what actions it should take.
How to Write Code in Java with a Semicolon?
To write a Java program, it is necessary to open a text editor, type in the code, and save it as a .java file. Following the syntax for Java, each statement in the program must contain a semicolon to terminate it.
Here is an example of a basic program in Java:
public class Calculator
{
public static void main(String[] args)
{
int a=10, b=6;
int sum = a + b;
System.out.println("The sum of a and b is:" + sum);
}
}
Note: Each statement in the code shown above is ended with a semicolon.
