The resultant is a new string. It takes an extra instruction to create and initialize a StringBuilder object, and another instruction to convert its final value to a String, but you might recover this time because StringBuilder can perform faster. Concatenation in C++ StringBuilder is class provides append() method to perform concatenation operation. Interpolation and concatenation play the same role, but often one ends up being more elegant than the other and makes the code easier to maintain. It is an operation of clipping one string to the end of another string. The String concatenation operator can concatenate not only String but primitive values also. The code concatenates the smaller strings to create the long string literal. After concatenation, JVM will create a new object and store string "Java Programming" in that object. The term"concatenation" literally means to merge two things together. In advance its constructor can also accept optional arguments, prefix and suffix. The following code combines an array of words using both methods: At last, you can use LINQ The general syntax to achieve concatenation is given below: (data type) (concatenation operator) (data type)= (concatenated expression) Consider two strings: hello="hello" and world=" world" The concatenation syntax in different programming languages is given below.
