How to create readable passing arguments? Java -

i have main class. want run @ command prompt , use arguments choose between switch cases.

public static void main(string[] args) throws interruptedexception, ioexception{      string response = null;     string input = args[0];      switch (input) {     case "createorder":         string path1 = "order?customer_id=1";         string body1 = file.getorderxml("2");         body1 = header + body1;         response = httpconnector.getinstance().execute("post", path1, body1);         system.out.println("order id "+response);         break;      case "sendorder":         string path2 = "cards?order_id=";         string ordernumber2 = args[1];         path2 += ordernumber2;         string body2 = file.getcardxml("1", emv, perso);         response = httpconnector.getinstance().execute("post", path2, body2);         system.out.println("card record: "+response);         break;      case "sendorders":         string path3 = "cards?order_id=";         //"string" order id         string ordernumber3 = args[1];         path3 += ordernumber3;         //"string" quantity         string qtt = args[2];         string body3 = file.getcardxml(qtt, emv, perso);         string[] lines = body3.split("\r\n|\r|\n");         int number = lines.length;         for(int = 0; < number ; i++){             response = httpconnector.getinstance().execute("post", path3, lines[i]);             system.out.println("card record: "+response);         }         break;      case "combined":         string paths = "order?customer_id=1";         string paths2 = "cards?order_id=";         string response2 = "";         //"string" quantity         string qtt2 = args[1];         string body4 = file.getorderxml(qtt2);         body4 = header + body4;         response = httpconnector.getinstance().execute("post", paths, body4);         system.out.println("order id "+response);         thread.sleep(2000);         //send card order         string result2 = new getxmlfile().getcardxml(qtt2, emv, perso);         body4 = header + result2;         string[] lines2 = body4.split("\r\n|\r|\n");         int number2 = lines2.length;         paths2 = paths2 + response.replace("\r\n", "");         for(int = 0; < number2 ; i++){             response2 += httpconnector.getinstance().execute1(paths2,lines2[i]);             system.out.println("card record: "+response2);         }         break;      case "0":         system.exit(0);         break;     }     system.in.read(); } 

in cmd: java -jar restclientnogui.jar "createorder" (to run 1st switch case)

so question how create "variable"(or other naming, not sure is.) in front of args?

example:

java -jar restclientnogui.jar /method="createorder" (for 1st switch case)

java -jar restclientnogui.jar /method="sendorder" /orderid="1234" (for 2nd switch case)

you use http://commons.apache.org/proper/commons-cli/. if want yourself, you'll parse command-line argument , set appropriate input based on prefix. this:

string input = args[0]; string[] keyval = input.split("="); string input1 = null; if(keyval[0].equals("method")){      input1 = keyval[1]; }
