This is a common error while accessing a which has below listed issues:

If you want Need to convert a date from a one format to another date format, please find the code below to do the same using Java.
You can have it as a generic Utility in your application’s Utility function.
/**
* Return string with formatted date
* @param inputdate Date String which needs conversion
* @param inputDateFormat Format of the input date
* @param outputDateFormat Format which date should be converted
* @return the output formated String
*/
private String convertDateFormat(String inputdate, String inputDateFormat, String outputDateFormat){
String outputDate = null;
SimpleDateFormat sdfSource = new SimpleDateFormat(inputDateFormat);
try {
Date date = sdfSource.parse(inputdate);
sdfSource = new SimpleDateFormat(outputDateFormat);
outputDate = sdfSource.format(date);
} catch (Exception e) {
e.printStackTrace();
}
return outputDate;
}
Let me know if you find a better way to do this.
Hope this helps !
Thanks,

Cause:
This is a standard error while making build in maven on Windows.
It occurs when your path contain’s special characters like ‘&’, ” etc.
Remove ampersand from the path and this should solve the problem. This is because mvn.bat cannot handle these characters in windows.
Solution: Remove ampersand “&” or special characters from path or username
Example:
Path: D:\workspace\dev&test\project1\mvn clean install (Error)
Rename the folder dev&test to devtest
Hope this Helps !
LinkedHashMap or HashMap ? January 1, 2008
Posted by ninadgawad in Java.Tags: coding, Java
5 comments
The Class LinkedHashMap is an extension of HashMap with specific feature of retaining the insertion order. Hence useful when order of key-value pairs are to be retained. Also if one inserts the key again into the LinkedHashMap the original orders is retained. Such Collection is useful when you want to covert a record fetched from the database into a Java Object. The main advantage with this is that now we can shift the sorting logic of retrieved data into database rather than writing custom code here; that help in boosting performance.
Java Docs available @ http://java.sun.com/javase/6/docs/api/java/util/LinkedHashMap.html
Example Code:
import java.util.Iterator;
import java.util.LinkedHashMap;
class LinkedHashMapEx1 {
public static void main(String[] args) {
LinkedHashMap map = new LinkedHashMap();
// Add some elements
map.put(“A”, “dataElement-1”);
map.put(“B”, “dataElement-2”);
map.put(“C”, “dataElement-3”);
map.put(“B”, “dataElement-4”);
// List the entries
for (Iterator it=map.keySet().iterator(); it.hasNext(); ) {
Object key = it.next();
Object value = map.get(key);
System.out.println( “Key = “+ key.toString() + ” Value = ” + value.toString() );
}
}
}
