- Method Detail
  - arraycopy
```
public static void arraycopy(Object src,
                             int srcOffset,
                             Object dest,
                             int destOffset,
                             int length)
```
    Copies one array to another.
  - currentTimeMillis
```
public static long currentTimeMillis()
```
    Current time expressed in milliseconds. In the TiJOS, this is the number of milliseconds since the TiJOS has been on. (In Java, this would be since January 1st, 1970).
  - exit
```
public static void exit(int code)
```
    Terminate the application.
  - gc
```
public static void gc()
```
    Collect garbage
  - getProperty
```
public static String getProperty(String name)
```
    Returns null. In TiJOS, there are no system properties. So this function returns null.
    
    Parameters:
    
    name - name of the system property
    
    Returns:
    
    null
  - getProperty
```
public static String getProperty(String name,
                                 String def)
```
    Returns def. In TiJOS, there are no system properties. So this function returns def.
    
    Parameters:
    
    name - name of the system property
    
    def - default value that is returns if system property doesn't exist
    
    Returns:
    
    def
  - getRuntime
```
public static Runtime getRuntime()
```
    Get the singleton instance of Runtime.
  - identityHashCode
```
public static int identityHashCode(Object obj)
```
  - nanoTime
```
public static long nanoTime()
```
    Return the time since system start in nano-seconds
    
    Returns:
  - setErr
```
public static void setErr(PrintStream err)
```
    Redirect System.err
    
    Parameters:
    
    err - a PrintStream
  - setIn
```
public static void setIn(InputStream in)
```
    Redirect System.in
    
    Parameters:
    
    in - a InputStream
  - setOut
```
public static void setOut(PrintStream out)
```
    Redirect System.out
    
    Parameters:
    
    out - a PrintStream
