是否可以执行随机切换来在请求之间分散负载，类似于在Scala中这样做？我找不到任何关于如何在Java中做到这一点的资源。
示例代码：

public static final ChainBuilder teacherCreateAssignmentsSetup = group("teacherCreatesAssignmentsSetup").on(
            exec(sessionSetSessionVariable)
                    .exec(session -> session.set("teacherRefId", getUniqueIdFromTokenSub(session)))
                    .exec(createEdCtsAssignment)
                    .exec(session -> {
                        log.info("assignment is :" + session.getString("studentsAssignment"));

                        return session;
                    })
                    .randomSwitch(
                            50.0 -> exec(nextRequest),
                            50.0 -> exec(anotherRequest)
                    )
    );
