In Java it is possible to convert String to Object in following way.

1. Using assign operator

public class Example1 {

    public static void main(String[] args) {
        String str = "abc";
        Object obj = str;
        System.out.println(obj); // abc
    }
}

Output:

abc

2. Explicit casting

public class Example2 {

    public static void main(String[] args) {
        String str = "abc";
        Object obj = (Object) str;
        System.out.println(obj); // abc
    }
}

Output: 

abc

Note that Casting 'str' to 'Object' is redundant

3. Print String class and Superclass name

public class Example3 {

    public static void main(String[] args) throws ClassNotFoundException {
        Class clazz = Class.forName("java.lang.String");

        System.out.println("class name: " + clazz.getName());
        System.out.println("super class name: " + clazz.getSuperclass().getName());
    }
}

Output:

class name: java.lang.String
super class name: java.lang.Object
