One case in a switch statement

The main Javadoc is in SwitchStmt

Java 1.0-11

switch (i) {
  case 1:
  case 2:
    System.out.println(444);
    break;
  default:
    System.out.println(0);
}
This contains three SwitchEntrys.
The first one has label 1 and no statements.
The second has label 2 and two statements (the println and the break).
The third, the default, has no label and one statement.
All of them are of type STATEMENT_GROUP.

Java 12-

    case 1 -> 15*15;
    case 2 -> { a++; b++; }
    case 3 -> throw new Exception();
These are three new variants.
The first one is of type EXPRESSION and stores its Expression in an ExpressionStmt which is stored as the first and only statement in statements.
The second one is of type BLOCK and stores its BlockStmt as the first and only statement in statements.
The third one is of type THROWS_STATEMENT and stores its ThrowStmt as the first and only statement in statements. 
    case MONDAY, FRIDAY, SUNDAY -> 6;
Multiple case labels are now allowed. 
    case 16*16, 10+10 -> 6;
Many kinds of expressions are now allowed.

cloneback to summary
public SwitchEntry clone()

Overrides com.github.javaparser.ast.Node.clone.

Doc from java.lang.Object.clone.

Creates and returns a copy of this object. The precise meaning of "copy" may depend on the class of the object. The general intent is that, for any object x, the expression: 

x.clone() != x
will be true, and that the expression: 
x.clone().getClass() == x.getClass()
will be true, but these are not absolute requirements. While it is typically the case that: 
x.clone().equals(x)
will be true, this is not an absolute requirement.

By convention, the returned object should be obtained by calling super.clone. If a class and all of its superclasses (except Object) obey this convention, it will be the case that x.clone().getClass() == x.getClass().

By convention, the object returned by this method should be independent of this object (which is being cloned). To achieve this independence, it may be necessary to modify one or more fields of the object returned by super.clone before returning it. Typically, this means copying any mutable objects that comprise the internal "deep structure" of the object being cloned and replacing the references to these objects with references to the copies. If a class contains only primitive fields or references to immutable objects, then it is usually the case that no fields in the object returned by super.clone need to be modified.

Returns:SwitchEntry

a clone of this instance.
