Thames & Kosmos Code Gamer - Extending Conditions with else and else if

You can also extend an
if
instruction with an
else
statement. The
else
statement is carried out if and
only if the condition is not fulfilled.
// if instruction with else statement
if (Condition) {
/
/ The following is only carried out
/
/ if the condition is fulfilled.
Instruction 1;
I
nstruction 22;
...
} else {
/
/ This block is carried out if
/
/ the condition is not fulfilled.
I
nstruction 3;
Instruction 4;
}
Finally, you can build in the additional block
else if
to check another condition if the first one is not
fulfilled.
// if instruction with else block
if (Condition 1) {
/
/ The following is only carried out
/
/ if the condition is fulfilled.
Instruction 1;
I
nstruction 2;
...
} else if (Condition 2){
/
/ This block is carried out if
/
/ the condition is not fulfilled.
I
nstruction 3;
Instruction 4;
} else {
/
/ This block is carried out if
/
/ none of the previously checked
/
/ conditions are fulfilled.
I
nstruction 5;
...
}
You can also omit the closing
else
statement. In
addition, you can line up as many
else if
statements in a row as you like.
