1. Java if Statement
The syntax of if-then statement in Java is:
if (expression)
{ // statements }
Example1
public static void main(String[] args) {
// TODO code application logic here
int number =0;
if (number > 0)
{
System.out.println("Number is positive.");
}
}
Example2
public static void main(String[] args) {
// TODO code application logic here
int password =123;
if (password==123)
{
System.out.println("Access Grandted.");
}
}
Java if...else (if-then-else) Statement
The if statement executes a certain section of code if the test expression is evaluated to true. The if
statement can have optional else statement. Codes inside the body of else statement are executed if the
test expression is false.
Example1
int number =5;
if (number > 1)
{
System.out.println("Number is greater than 1.");
}
else
{
System.out.println("Number is less than 1.");
}
}

2. Example2
public static void main(String[] args) {
// TODO code application logic here
String Username="MNHS246";
if (Username.equals("MNHS246"))
{
System.out.println("Access Granted");
}
else
{
System.out.println("Access Denied");
}
