The new release is more evolutionary than revolutionary, Reinhold said.
The new version of Java Standard Edition will feature improved file system support and concurrent operations
Java 7 radically expands the amount of functionality it offers for non-Java languages, which should improve performance for programs written in these languages,
Rose explained. Non-Java languages can now make method calls with the JVM. A new instruction, called invokedynamic, allows programmers to import the logic of their non-Java compilers
The JSR-203 file API (application programming interface) specification supplants the java.io.file package.
The API can read a wider array of file attributes and can offer more information when errors occur, said Staffan Friberg, a principal product manager in the Oracle Java Platform group, in a later session. It can detect when the contents of a file have been changed. It also can work with symbolic links, for those operating systems that use symbolic links.
The API also speeds file system operations, thanks to the fact that the new API makes fewer calls to the operating system, Friberg said.
there is lot more new in JAVA 7…..
