Without the break statement, the Java switch/case block looks very deceptive. Code: public class TestCase { public static void ... Test: C:\tmp>java TestCase No arguments One argume...

This topic comes up once in a while: I need to generate a random string in JavaScript to get around browser (IE) cacheing. Method 1 (not really random, but a new value every millisecond): function randomString() { return '' + n... Method 2 (generate a random alpha-numerical string): function randomString(length) { var chars =...

This example demonstrates the general steps in creating a custom Java class loader. Normally a class loader would consult its parent class loader when asked to load a class. If it's not loaded by the parent class loader, then the class loader would try to load the class on its own. This class loader tries to load the requested class on its own first, and delegates to the parent only when a java.lang.SecurityException is thrown (which happens when it tries to load core Java classes such as java.lang.String ). The classes are loaded from CLASSPATH through the getResourceAsStream call. It's important to note that when a class is loaded with a certain class loader, all classes referenced from that class are also loaded through the...

substr returns a substring beginning at a specified location and having a specified length . substring returns a substring by specifying the start and end index. s = 'She-sells-sea-shells-by-the-sea-shore'; s.... But really, providing two options does not make things better. Either one gets the jobs done. Two options just create more confusion.

Java Java requires the expression to be type boolean . There are only two possible values for a boolean : true or false . Using any other data type in a boolean context (such as an if condition) is an error. C# C# supports a strict boolean type, bool . Statements that take conditions, such as while and if , require an expression of a boolean type. C# disallows this "integer meaning true or false" approach on the grounds that forcing programmers to use expressions that return exactly bool can prevent certain types of programming mistakes such as if (a = b) (use of = instead of == ). Perl A scalar value is interpreted as TRUE in the Boolean sense if it is not...
