    Default variable in for loop

    Hi there,
    I'm very begginer at Java and I want to modify a code. Here is the entire code:
    var NodeName1 = "Curve1"; 
    var NodeName2 = "Curve2"; 
    var NodeName3 = "Curve3"; 
    var NodeName4 = "Curve4"; 
    var NodeName5 = "Curve5"; 
    var NodeName6 = "Curve6";
     
    var count = ag.fm.FeatureCount;
    var num1 = 0;
    var Yes = agc.Yes;
    for (var i = 0; i < count; i++) {
     
      var current = ag.fm.Feature(i);
      var Name = current.Name;
     
      if (Name.toLowerCase() == NodeName1.toLowerCase()) { 
        current.CurveRefresh = Yes; 
        num1 += 1;
      } else if (Name.toLowerCase() == NodeName2.toLowerCase()) {
        current.CurveRefresh = Yes;
        num1 += 1;
      } else if (Name.toLowerCase() == NodeName3.toLowerCase()) {
        current.CurveRefresh = Yes;
        num1 += 1;
      } else if (Name.toLowerCase() == NodeName4.toLowerCase()) {
        current.CurveRefresh = Yes;
        num1 += 1;
      } else if (Name.toLowerCase() == NodeName5.toLowerCase()) {
        current.CurveRefresh = Yes;
        num1 += 1;
      } else if (Name.toLowerCase() == NodeName6.toLowerCase()) {
        current.CurveRefresh = Yes;
        num1 += 1;
      } else if (num1 == 6) {
        break;
      }
    }
    agb.regen();
    Actually i want to make this code as short as possible... maybe using for loop to prevent from repeating some statements... can anyone help me?

    Default Re: variable in for loop

    One reduction would be to only call Name.toLowerCase() only once and save the results in a variable that would be used in the if statements instead of repeatedly calling it.
    Also define if NodeName1 etc does not require mixed case, define it with lower case and remove the calls to toLowerCase()
    Another change might be to use a switch statement instead of if/else if statements.
    If you don't understand my answer, don't ignore it, ask a question.

    Default Re: variable in for loop

    Dear friend(s),
    Honestly, I’m not a java programmer and I know nothing but a little about java… if anyone can do this for me (I mean rewriting the code to be shortened) I’ll greatly be appreciated…
    Also, I don’t know if we can do something with the first part of the code:
    var NodeName1 = "Curve1"; 
    var NodeName2 = "Curve2"; 
    var NodeName3 = "Curve3"; 
    var NodeName4 = "Curve4"; 
    var NodeName5 = "Curve5"; 
    var NodeName6 = "Curve6";
    for example, defining a for loop or something else… many thanks
