Calling the class in java, using the name of a class from a string

Question

Is there any easy way to achieve this.

Let's say I have an array of string with the name of POJO's in there and I"m trying to print all the list of attributes, is there any way to achieve this easily?\

String [] nameofClass;
for(String name:nameofClass)
name.class.getDeclaredFields();

Thanks

By name of POJO do you mean the name of a variable or the class itself? — Sotirios Delimanolis

Class.forName(name).getDeclaredFields() within your for loop is probably what you're looking for.

Note that name should be the full path of the class, i.e. not only TheClass but the.package.to.TheClass.

Yes you can. See the example given below:

        String [] nameofClass = {"java.lang.Object","java.lang.Thread"};//Give complete path of the class
        try{
            for(String name : nameofClass)
            {
                Class cl = Class.forName(name);
                System.out.println(cl);
                System.out.println("\t"+java.util.Arrays.toString(cl.getDeclaredFields()));
            }
        }catch(Exception ex){System.out.println(ex);}
