Answer / kartik sharma
In case of String s=new String("vali"); , a memory in the heap is allocated to the variable of the class String, and then the value is given to the variable s="vali". Using new operator , we can allocate the memory to the instance of the class.
But in String s="vali" , only the variable s is given the value as vali but there is no permanent memory given to the variable in heap.
