Write a Java program to create a TreeSet of colors and add elements in random order, then print the set to demonstrate its natural ordering. Write a Java program to create a TreeSet of colors, convert each color to lowercase before insertion, and then display the sorted unique set. ...
这个例子把面向字符与面向字节的流混合了起来,输入(in)用Reader类,而GZIPOutputStream的构造器只能接受OutputStream对象,不能接受Writer对象,在打开文件时,GZIPInputStream可以转换成Reader。 用Zip进行多文件保存 支持Zip格式的java库更全面。利用该库可以保存多个文件,它甚至有一个独立的类,使得读取Zip文件更方便。可以...

When we need to iterate over all the elements, we can use afor-each loop: This loop will print: The output looks better now, but our inner map still isn’t pretty-printed, so we have to manually handle complex structures. To format our inner entries, let’s implement a helper function...
Another approach to obtaining distinct characters is by leveraging Java Streams. Streams provide a concise and functional way to work with collections, including extracting distinct elements. Here’s an example: @Test public void givenString_whenUsingStreams_thenFindDistinctCharacters() { Set<Character>...
