输入退出时如何返回主菜单

如果选择4（退出），我想返回主菜单aka“eventSelection”。 现在我将它作为返回退出整个程序。

import java.util.*; public class SchedulingProgram { public static void main (String [] args) { eventSelection(); } public static void eventSelection() { Scanner sc = new Scanner(System.in); System.out.println("Select Scheduling Action"); System.out.print("Add an Event = 1. \nDisplay Events = 2.\nPrint Alert = 3. \nExit = 4. \nINPUT : "); int actionSelect = sc.nextInt(); if (actionSelect >= 1 && actionSelect <= 4) { if (actionSelect == 1) { addEvent(); } else if (actionSelect == 2) { displayEvent(); } else if (actionSelect == 3) { printAlert(); } else if (actionSelect == 4) { return; } } else { System.out.println("Error : Choice " + actionSelect + " Does Not Exist."); } }
