The if-else statement is used when we want to execute a certain statement if a condition is true, and a different statement if the condition is false.
The if-else statement has the form,
if( boolean_expression )
statement;
else
statement;
or can also be written as,
if( boolean_expression ){
statement1;
statement2;
. . .
}
else{
statement1;
statement2;
. . .
}
For example, given the code snippet,
int grade = 68;
if( grade > 60 ) System.out.println("Congratulations!");
else System.out.println("Sorry you failed");
or
int grade = 68;
if( grade > 60 ){
System.out.println("Congratulations!");
System.out.println("You passed!");
}
else{
System.out.println("Sorry you failed");
}
