com.github.javaparser.ast.Node

com.github.javaparser.ast.stmt.Statement

com.github.javaparser.ast.stmt.IfStmt

All Implemented Interfaces:

NodeWithCondition<IfStmt>, NodeWithRange<IfStmt>, NodeWithTokenRange<IfStmt>, Observable, Visitable, HasParentNode<IfStmt>, Cloneable

public final class IfStmt
extends Statement
implements NodeWithCondition<IfStmt>

An if-then-else statement. The else is optional.
In if(a==5) hurray() else boo(); the condition is a==5, hurray() is the thenStmt, and boo() is the elseStmt.
