如何给出选项，选完之后再返回选项菜单，继续让用户选择？不用GUI
我做个菜单选项如下，每次选完之后就跳过去了，没法自动再给出菜单选项，用什么办法能实现返回菜单选项？
import java.util.*;
import java.io.*;
import java.lang.Math;
public class GPS {
public static String readMenu(){
String inPut = " ";
try{
InputStreamReader isr = new InputStreamReader(System.in);
BufferedReader br = new BufferedReader(isr);
System.out.println( "Now Choose what you want to do: ");
System.out.println( "1: Search for state ");
System.out.println( "2: Search for city ");
System.out.println( "3: Set current city ");
System.out.println( "4: Show current city ");
System.out.println( "5: Find n closest ");
System.out.println( "6: Find shortest path ");
System.out.println( "7: Quit ");
System.out.println( "...................... ");
System.out.println( "Enter the number to choose the menu. ");
inPut = br.readLine();
}
catch(IOException ioe){
System.err.println( "IOException: " + ioe.getMessage());
}
return inPut;
}
public static void main(String[] args) throws IOException{
int menu = 0;
menu = Integer.parseInt(readMenu());
if(menu == 1){
System.out.println( "Now enter the state name, for example: New York ");
stateName = readInput();
searchState(stateName, cityNumInt, cities);
}
if(menu == 2){
System.out.println( "Now enter the city name, for example: New York City ");
cityName = readInput();
searchCity(cityName, cityNumInt, cities);
}
if(menu == 3){
System.out.println( "Now enter the city name, for example: New York City ");
currentCity = readInput();
currentCityID = setCurrentCity(currentCity, cityNumInt, cities);
}
if(menu == 4){
System.out.println( "The current city ID is " + currentCityID);
System.out.println( "name = " + cities[currentCityID].name);
System.out.println( "state = " + cities[currentCityID].state);
System.out.println( "latCord = " + cities[currentCityID].latCord);
System.out.println( "longCord = " + cities[currentCityID].longCord);
}
if(menu == 5){
System.out.println( "Now enter the 'n ' you want: ");
numClosest = Integer.parseInt(readInput());
calculatcities(currentCityID, numClosest,cityNumInt, cities);
}
if(menu == 6){
System.out.println( "This will find the shortest path of 2 cities: ");
System.out.println( "Enter the first city: ");
firstCity = readInput();
searchCity(firstCity, cityNumInt, cities);
System.out.println( "Enter the second city: ");
secondCity = readInput();
searchCity(secondCity, cityNumInt, cities);
shortestPath(firstCity, secondCity, cityNumInt, cities);
}
if(menu == 7){
System.out.println( "Thank you. ");
}
}
还有，就是能不能把这么多if都放到子函数readMenu()里面，让main（）函数更好看点？
多谢多谢
[解决办法]
为整个部分提供一个选项
if(wannerBack==true)
readMenu();
