                             int srcBegin,
                             Object dst,
                             int dstBegin,
                             int count)

currentTimeMillis

public static long currentTimeMillis()

nanoTime

public static long nanoTime()

identityHashCode

public static int identityHashCode(Object obj)

getProperty

public static String getProperty(String name)

getProperty

public static String getProperty(String key,
                                 String def)

getProperties

public static Properties getProperties()

setProperties

public static void setProperties(Properties p)

setProperty

public static String setProperty(String key,
                                 String value)

lineSeparator

public static String lineSeparator()

Returns the system-dependent line separator string. It always returns the same value - the initial value of the system property line.separator.

On UNIX systems, it returns "\n"; on Microsoft Windows systems it returns "\r\n".

exit

public static void exit(int exitCode)

setOut

public static void setOut(PrintStream out)

setIn

public static void setIn(InputStream in)

setErr

public static void setErr(PrintStream err)
