Let us see in detail.
if Statement
This statement checks a particular condition. If the condition is satisfied, then the statement or a group of statements
inside the “if” block will be executed.
Syntax:
if(Condition)
{
Statement 1;
Statement 2;
.
.
}
Note: If there is single statement after the condition, then use of curly brackets is optional.
Flowchart:
if(condition)?
Statement
For example,
1. if(a%5==0)
System.out.println(a+ " is divisible by 5");
Here, the control statement checks whether the number stored in the variable a is divisible by 5. If it is divisible, the
following message will be printed, otherwise, the message will be ignored.
2. if(a%5==0 && a%2==1)
{
System.out.println("The number is divisible by 5");
System.out.println("It is an odd number");
}
Here, if a%5 returns 0 and a is an odd number, the two messages will be printed.
3. if(c==0)
{
c=a++ + ++b;
System.out.println("c= "+ c);
}
System.out.println("Outside if block");
Here, if c==0, then the value of c will be changed to 15 and displayed. However, if c==0 is false, the message
“Outside if block” will be displayed.
