システムプロパティ

(KAB-studioからのおしらせです)

// Sample.java
import java.util.Properties;
import java.util.Enumeration;

public class Sample
{
    public static void main( String[] args )
    {
        // システムプロパティ"java.runtime.name"を取得します。
        String runtime = System.getProperty( "java.runtime.name" );
        System.out.println( "java.runtime.name=" + runtime );
        // java.runtime.name=Java(TM) 2 Runtime Environment, Standard Edition

        // SystemクラスのgetProperties()メソッドで、システムプロパティ
        // 一覧を取得します。
        Properties properties = System.getProperties();
        Enumeration enumeration = properties.keys();
        for( ; enumeration.hasMoreElements(); )
        {
            String key = (String)enumeration.nextElement();
            String value = (String)properties.get( key );
            System.out.println( key + "=" + value );
        }
