# Interface: com.pnfsoftware.jeb.core.units.code.java.IJavaSwitch

Java AST interface to represent `switch` statements. They support integer keys \(standard switch\), String keys, and Enum keys. Limitation: These objects do not support case\-block replacement. 

 A switch\-statement consists of an expression, zero or more cases and an optional default case. 

 Example:  

```

 switch(exp)
   case c0: b0
   case c1: b1
   default: b2
 
```
