if-else statement Start
Some programs need to choose any one of the two
actions depending on the requirement of the program.
In Java, an if-else statement executes the if block if the Input values a & b
condition is true. Otherwise, the else block will be
executed.
Syntax:
if (condition) if (a==b) true Print "Equal"
{
// Code to execute if the condition is true
} false
else
{ Print "No Equal"
// Code to execute if the condition is false
}
