Both these expressions are used to create string objects. But the difference lies in the memory management of the objects created.

Both these expressions are used to create string objects. But the difference lies in the memory management of the objects created. Let's consider the first case: String s1="Hello"; In the above statement, the string object s1 is created and the value of the string "Hello" is assigned to the string object s1. JVM assigns this value to the object and stores it in a separate block of memory called the string constant pool. Now if another String object is created, say String s2="Hello"; Then, JVM checks if any string object with the same value already exists in the string constant pool. If so, then JVM assigns a reference of the existing object to the new variable. Hence we run: String s1="hello"; String s2="hello"; System.out.println(s1==s2) Then the output will be True because s1 and s2 are references to the same object. Now let us consider the second case: String s1 new String("Hello"); We create an object s1 using the new keyword. This will create two objects, one in the string Constant Pool(SCP) and the other one in the Heap Memory and one reference variable, and S1 will refer to the object in heap memory. Now if we create another object String s2= new string("hello"); Then, it'll create a new object s2 with the same value, irrespective of whether it is present in the heap memory or not. read less
