ELSE IF Ladder in Java

Use if to specify a block of code to be executed, if a specified condition is true. Use else to specify a block of code to be executed, if the same condition is false. Use else if to specify a new condition to test, if the first condition is false.

The else if condition is checked only if all the conditions before it (in previous else if constructs, and the parent if constructs) have been tested to false.

Syntax

if ( condition 1 )
{
    // block of statement to be executed if condition is true ;
}
else if ( condition 2 )
{
    // block of statement to be executed if the condition1 is false condition2 is true ;
}
else
{
    block of statement to be executed if the condition1 is false condition2 is False ;
}
