Guys, I tried following code : Object ob=new int[]{1,3,5}; //Line 1 int[] x=(int[])ob; System.out.println(x[0]); // System.out.println(ob[1]); Line 4*** This line gives an error. What I do not understand is, when Line 1 is acceptable to compiler, why not Line 4??
When you use the index reference operator, ie., [], the operand has to be an array type. In your code, ob is declared as an Object, not an array. Hence the error. Hope that helps, Ajith

Upendra, What i know is Arrays do not have a type hierarchy but arrays are considered as instance of Object.Hence its possible to convert Arrays to Object,but What i think is the Object AND arrays just hold the reference to the memory allocations but not the actual objects,hence When u try to access array indexes with O[]. will only point to the array object but not the actual array. If anybody knows the answer pls let me know. Prasad ------------------
