This question involves two classes that are used to process log messages. A list of sample log messages is given below.

CLIENT3:security alert – repeated login failures 
Webserver:disk offline
SERVER1:file not found
SERVER2:read error on disk DSK1
SERVER1:write error on disk DSK2
Webserver:error on /dev/disk

Log messages have the format machineId:description, where machineId identifies the computer and description describes the event being logged. Exactly one colon (“:”) appears in a log message. There are no blanks either immediately before or immediately after the colon.

The following LogMessage class is used to represent a log message.

public class LogMessage
{
    private String machineId;
    private String description;

    /** Precondition: message is a valid log message. */ 
    public LogMessage(String message)
    { /* to be implemented in part (a) */ }

    /** Returns true if the description in this log message properly contains
    * keyword; false otherwise.
    */
    public boolean containsWord(String keyword)
    { /* to be implemented in part (b) */ } 

    public String getMachineId()
    {  return machineId;  }

    public String getDescription()
    {  return description;  }

    // There may be instance variables, constructors, and methods that are not shown. 
}

Write the constructor for the LogMessage class. It must initialize the private data of the object so that getMachineId returns the machineId part of the message and getDescription returns the description part of the message.
