In Java SE 7 and later, a single catch block can handle more than one type of exception. This feature can reduce code duplication and lessen the temptation to catch an overly broad exception. Consider the following example, which contains duplicate code in each of the catch blocks: catch (IOException ex) { logger.log(ex);. Inside this dialog you will want to add 3 Environment Variables to the System. JAVA6_HOME = { Location of Java 6 Installation }; JAVA7_HOME = { Location of Java 7 Installation }; JAVAHOME = %JAVA7HOME% - this variable will change, when you want to a different JDK.

This new proposal for Java 7 wants to improve the interfaces allowing to add new methods to existing interfaces. The classes implementing the interfaces doesn't need implements these methods. The implementation of these methods are provided using static methods. This could be called virtual extension. Memory leaks are a very real problem in Java and the JVM can only help so much.. Nevertheless, memory leaks can still occur in Java applications... The problem was partially removed in Java 7 when the ability to automatically close all types of streams was introduced into the try-with-resource clause. Building with JDK8 just involved updating our Java buildpack to set JAVA_HOME to /usr/java/jdk1.8.0_40 (or wherever you put JDK8 in the previous step). It's important to note that you're not building Java 8 class files at this point, and you can't start using Java 8 features. You're still compiling Java 7 class. One of the Java 7 features is underscores in numeric literals. You can place underscores between digits of any numeric literal like int, byte, short, float, long, double. Using underscores in numeric literals will allow you to divide them in groups for better readability. Let's see underscores in numeric literals in.
