Java String Trim Leading & Trailing Whitespace
The trim() method will only remove all leading and trailing whitespace. It will not remove whitespace in the middle of your String object. So whitespace is defined as one ore more spaces in a row that are either at the beginning or ending of your String.
String jcdString = " Java Code Depot Rocks! "; jcdString.trim()

System.out.println("\nBefore Trim: "+jcdString1);
System.out.println("After Trim: "+jcdString1.trim());
//Trim all leading/trailing whitespace and modify variable

jcdString2 = jcdString2.trim();
System.out.println("\njcdString2 Contents: "+jcdString2);
}
