When you store a String asString str1 = "Hello";directly, then JVM creates a String object with the given value in a separate block of memory known as String constant pool.And whenever we try to create another String asString str2 = "Hello";JVM verifies whether any String object with the same value exists in the String constant pool, if so, instead of creating a new object JVM assigns the reference of the existing object to the new variable.And when we store String asString str = new String("Hello");using the new keyword, a new object with the given value is created irrespective of the ...

As we know that both TRUNCATE and DELETE statement will not delete the structure of the table but still it is better to use TRUNCATE statement rather than DELETE statement. DROP statement will delete table’s structure also. Syntax TRUNCATE statement TRUNCATE table table_name: Syntax DROP statement DROP table table_name:
The C++ programming language has a history going back to 1979, when Bjarne Stroustrup was doing work for his Ph.D. thesis. He began work on "C with Classes", which as the name implies was meant to be a superset of the C language. His goal was to add object-oriented programming into the C language, which was and still is a language well-respected for its portability without sacrificing speed or low-level functionality.His language included classes, basic inheritance, inlining, default function arguments, and strong type checking in addition to all the features of the C language. The first C with Classes compiler ... Read More
