Compact Strings -  Java 9 Feature

Motivation The current implementation of the String class stores characters in a char array, using two bytes (sixteen bits) for each character. Data gathered from many different applications indicates that strings are a major component of heap usage and, moreover, that most String objects contain only Latin-1 characters. Such characters require only one byte of storage, hence half of the space in the internal char arrays of such String objects is going unused Description We propose to change the internal representation of the String class from a UTF-16 char array to a byte array plus an encoding-flag field. The new String class will store characters encoded either as ISO-8859-1/Latin-1 (one byte per character), or as UTF-16 (two bytes per character), based upon the contents of the string. The encoding flag will indicate which encoding is used. String-related classes such as AbstractStringBuilder, StringBuilder, and StringBuffer will be updated to use the same representation, as wi...

It is dynamically downloaded from a web server to a browser and it is executed in the environment provided by the browser.

The third line is the comment entry which is used only for applet viewer to execute the applet using the HTML source code. The next line declares the FirstApplet class which extends Applet class. Note that each applet created by user must extend the Applet class. There is a paint() method defined...
