That’s how you can use enumerations for string values:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 | /* * ISO 3166 */ public enum Country { DE { @Override public String toString() { return "Germany"; } }, IT { @Override public String toString() { return "Italy"; } }, US { @Override public String toString() { return "United States"; } } } |
1 2 3 4 5 6 | public static void main(String[] args) { System.out.println(Country.DE); // Germany System.out.println(Country.IT); // Italy System.out.println(Country.US); // United States } |
With JUnit 4 it is pretty simple to test if an exception has been properly thrown because you can use annotations:
1 2 3 4 5 6 7 8 9 10 11 12 13 | import static org.junit.Assert.fail; import org.junit.*; public class MyTestClass { @Test(expected = NoMatchFoundException.class) public void testSomething() throws NoMatchFoundException { // Your critical code here! fail(); } } |
If you are using JUnit 3 then it is not that easy because you don’t have annotations. That’s why you have to catch exceptions in the test code:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 | import junit.framework.TestCase; public class MyTestClass extends TestCase { public void testSomething() throws NoMatchFoundException { try { // Your critical code here! } catch (NoMatchFoundException ex) {} } } |
Möchte man einen langen Batch-Befehl auf mehrere Zeilen aufteilen, so muss man den Zeilenumbruch maskieren (escapen). Der Zeilenumbruch wird mit einem ^ angedeutet.
Beispiel:
REM Einzeilig: echo Hello World. REM Zweizeilig: echo Hello ^ World.
JavaScript is able to zoom in and zoom out of a web page. All you need is just this (for 200% zoom):
window.parent.document.body.style.zoom=2.0;
In modern mobile devices and HTML5 browsers you can set the viewport content (for example the webpage zoom and webpage dimension) with a single meta tag:
<meta name="viewport" content="width=device-width,initial-scale=2.0,minimum-scale=2.0,maximum-scale=2.0, user-scalable=no">
If you want to do this with JavaScript, then you need a viewport meta-tag with empty content:
<meta name="viewport" content="" />
Then you can change the content by using JavaScript:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 | function setViewPort(viewPortContent){ var metas = document.getElementsByTagName('meta'); var i; if (navigator.userAgent.match(/iPhone/i)) { for (i=0; i<metas.length; i++) { if (metas[i].name == 'viewport') { metas[i].content = viewPortContent; } } } } var viewPortContent = 'width=device-width,initial-scale=2.0,minimum-scale=2.0,maximum-scale=2.0, user-scalable=no'; setViewPort(viewPortContent); |
If you want to constantly hide the address bar on mobile devices like iPhone, iPad and Android smartphones/tablets, then you have to scroll the window even if the device is turned:
1 2 3 4 5 6 7 8 9 10 | <script type="text/javascript"> function hideAddressBar(){ window.scrollTo(0, 1); } window.onload = hideAddressBar; window.onscroll = hideAddressBar; window.onresize = hideAddressBar; window.onorientationchange = hideAddressBar; </script> |
Short version:
<script> window.onload = window.onscroll = window.onresize = window.onorientationchange = function(){ window.scrollTo(0, 1); }; </script>
