Unable to find Java nio. File package

My java compiler can't find Java nio. File package consider:

import java.nio.file.*;
public class Test {
    public static void main(String[] args) { 
        Path currentRelativePath = Paths.get("");
    }
}

compile

bash$javac Test.java

to

Test.java:1: package java.nio.file does not exist
import java.nio.file.*;
                ^
Test.java:5: cannot find symbol
symbol  : class Path
location: class Test
    Path currentRelativePath = Paths.get("");
    ^
Test.java:5: cannot find symbol
symbol  : variable Paths
location: class Test
    Path currentRelativePath = Paths.get("");
                               ^

I am using Ubuntu 12.04. I think I have installed JDK 7 (see package java.nio.file does not exist)

bash$java -version
java version "1.7.0_25"
OpenJDK Runtime Environment (IcedTea 2.3.10) (7u25-2.3.10-1ubuntu0.12.04.2)
OpenJDK 64-Bit Server VM (build 23.7-b01,mixed mode)

Solution

You can use Java 1.7, but javac 1.6 or even 1.5

Maybe you can use

sudo update-alternatives --config javac

Configure it If you cannot select 1.7, you need to upgrade the JDK package
