jNote: This release is in preview. Features described here don’t become generally available until the latest general availability date that Salesforce announces for this release. Before then, and where features are noted as beta, pilot, or developer preview, we can’t guarantee general availability within any particular time frame or at all. Make your purchase decisions only on the basis of generally available products and features.
Conditional (If-Else) Statements
The conditional statement in Apex works similarly to Java.
1if ([Boolean_condition])
2 // Statement 1
3else
4 // Statement 2The else portion is always optional, and always
groups with the closest if. For
example:
1Integer x, sign;
2// Your code
3if (x <= 0) if (x == 0) sign = 0; else sign = -1;1Integer x, sign;
2// Your code
3if (x <= 0) {
4 if (x == 0) {
5 sign = 0;
6 } else {
7 sign = -1;
8 }
9}Repeated else if statements are also allowed.
For
example:
1if (place == 1) {
2 medal_color = 'gold';
3} else if (place == 2) {
4 medal_color = 'silver';
5} else if (place == 3) {
6 medal_color = 'bronze';
7} else {
8 medal_color = null;
9}
