Description

public static void simpleSort(int [] data)

The sorting method for interger array data.
The data will be rewritten.

public static void simpleSort(double[] data)

The sorting method for double floating array data.
The data will be rewritten.

public static int[] indexedSimpleSort(int[] data)

The sorting method for interger array of data.The data won't be changed.
Denotes the returned integers as indices, then the sorting result is as follow.

data[indices[0]]<= data[indices[1]]<= data[indices[2]] ....

public static int[] indexedSimpleSort(double[] data)

The sorting method for double floating array of data. The data won't be changed.

Denotes the returned integers as indices, then the sorting result is as follow.

data[indices[0]]<= data[indices[1]]<= data[indices[2]] ....

private static void indexedSwap(int[] indices, int i,int j)

Exchanges indices[i] with indices[j].

private static void swap(int [] data, int i,int j)

Exchanges data[i] with data[j].

private static void swap(double[] data, int i,int j)

Exchanges data[i] with data[j].

private static void printSort(String message, int [] data)

Prints the data.

private static void printSort(String message, double[] data)

Prints the data.

private static void printSort(String message, int[] data, int[] indices)

Prints the data and indices.

private static void printSort(String message, double[] data, int[] indices)

Prints the data and indices.

public String getASCIIControlString(String command)

parameters:
command - The command name.

Return:

The string representing the ASCII code, if the first character of command is an ASCII code, otherwise returns "".

Processing:

If the "c" key is presed with holding down the Ctrl key (ctrl+c), for example, the string of an action command given by the statement of ActionEvent.getActionCommand()is an ASCII code of "0x03". The probelem is that the "0x03" is an undefined character in Java.
This method checks whether the first character of the parameter is an ASCII code or not. If is's an ASCII code, then return the String representing the ASCII code, for example, "ctrl+c" in this case.

Example: the returned string for the ASCII code.
"0x01" ->"ctrl+a", "0x08" ->"ctrl+h" (Back space), "0x16" ->"ctrl+v", "0x18" ->"ctrl+x"
