The code snippet presented below shows you how to create a simple JTable component in a swing application. To create a JTable component we initialize it using the constructor that accept two parameters. The first parameter is the table’s row of data which type is Object[][], a two-dimensional array of Object. The second parameter is […]
This example show you how to use the BreakIterator.getSentenceInstance() to breaks a paragraphs into sentences that composes the paragraph. To get the BreakIterator instance we call the getSentenceInstance() factory method and passes a locale information. In the count(BreakIterator bi, String source) method we iterate the break to extract sentences that composes the paragraph which value […]
At first, it might look simple. We can just split the text using the String.split(), the word is split using space. But what if a word ends with questions marks (?) or exclamation marks (!) instead? There might be some other rules that we also need to care. Using the java.text.BreakIterator makes it much simpler. […]
When the strings must be compared multiple times, for example when sorting a list of strings. It’s more efficient to use CollationKey class. Using CollationKey to compare strings is generally faster than using Collator.compare(). You can not create CollationKey directly. Rather, generate them by calling Collator.getCollationKey() method. You can only compare CollationKey generated from the […]
We can use the java.text.Collator class to sort strings in language-specific order. Using the java.text.Collator class makes the string not just sorted by the ASCII code of their characters, but it will follow the language natural order of the characters. If the predefined collation rules do not meet your needs, you can design your own […]
To create an instance of a JColorChooser with a default or initial color such as Color.BLUE you can pass the Color object to the constructor of the JColorChooser component. The example below shows how to do it. package org.kodejava.swing; import javax.swing.*; import java.awt.*; public class JColorChooserDefaultColor extends JFrame { public JColorChooserDefaultColor() throws HeadlessException { initializeUI(); […]
