Java String transform() method

Java String transform() method

String transform() method added jdk 12.

This method allows the application of a function to this string. The function should expect a single String argument and produce an R result.
Any exception thrown by f() will be propagated to the caller.

Java Program Example:

class StringTransform{
public static void main(String args[]){
String str = "Transform";

}
}

Method:

public <R> R transform​(Function<? super String,​? extends R> f)
