Java-String Concatenation

String Concatenation

Java defines one operator for string object such as “+”, it is used to concatenate two string. For example, in the following program, the value of the variable ‘date’,’month’ and ‘year’ is being converted to a string that represents this value as a decimal digit character. This is prompted by the fact that it is combined with the string literal, “ “, using the + operator.
