Question

In ActionScript 2 and 3, we can access a member variable of a class like it is in an associative array.

for eg.,

//AS3 Code    
private var tempvar:String="Hello";

    function printString()
    {
       trace(this.tempvar);
      trace(this[tempvar]);// would print the same as above
    }

I was wondering if the same is possible in Java as well.

The reason I need this is because, I have some variables like the following in my java code

//java code
private String var_1, var_2, var_3, var_4;

To access these variables, I have to write 4 different statements

//java code
var_1="SomeValue1";
var_2="SomeValue2";
var_3="SomeValue3";
var_4="SomeValue4";

If it is in AS3, I could have done something like this

//AS3 Code
for( var i=1; i<=4;i++)
{
 this["var_"+i]="SomeValue"+i;
}

I’ll be a much happy coder if someone could let me know how to do the same in Java.

Thanks

I think you need to refactor your Java code…

You can use a Map<String, String> to achieve that.
