The implementation of the string concatenation operator is left to the discretion of a java compiler, as long as the compiler ultimately conforms to the java™ language specification.for example, the javac compiler may implement the operator with stringbuffer, stringbuilder, or java.lang.invoke.stringconcatfactory depending on the jdk. Leading and trailing whitespace characters in s are ignored. Each time you create a string literal, the jvm checks the string constant pool first. The implementation of the string concatenation operator is left to the discretion of a java compiler, as long as the compiler ultimately conforms to the java language specification.for example, the javac compiler may implement the operator with stringbuffer, stringbuilder, or java.lang.invoke.stringconcatfactory depending on the jdk version.
