Switch

I am new to using switches (this is my first one I've ever attempted), could somebody please tell me if this is proper/will work?

Code:java

 
 
switch(3) {
    case 1:
    if (args.length == 0) {
        do something;
    }
    break;
 
    case 2:
    if (args.length == 1) {
        do something;
    }
    break;
 
    case 3:
    if (args.length > 1) {
        do something;
    }
    break;
}
 

 

It works in the sense that it will always go to case 3.

 

@Sagacious_Zed What do I need to do then...?

 

This can explain it much better than I can

@Sagacious_Zed Thanks, I think I will just use else if though

 

specifically in your case, you should replace the 3 inside the switch statement with args.length

 

Try this :

Code:

switch(args.length){
    case 0://0 args
    {
        //...
    }
    break;
    case 1://1 arg
     {
        //...
    }
    break;
    default:// > 1 args
     {
        //...
    }
    break;
}

 

@Crash Thank you!
