package program;

import expression.Expression;

A Conditional consists of the condition expression and the two programs thenCase and elseCase with the intended semantics of execution the elseCase if the expression evaluates to 0 and the thenCase otherwise.

public class Conditional extends Program {
    public final Expression condition;
    public final Program thenCase;
    public final Program elseCase;

    public Conditional(Expression condition, Program thenCase, Program elseCase) {
        this.condition = condition;
        this.thenCase = thenCase;
        this.elseCase = elseCase;
    }
