This method extracts the characters in a string between "start" and "end", not Begin the extraction at position 2, and extract the rest of the string: If "start" is greater than "end", it will swap the two arguments: If "start" is less than 0, it will start extraction from index ind1, ind2 : An integer between 0 and 1 less than the length of the string. The + operator can be used between strings to Implementation Note: 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.
