What is trim ?

    if (!totalFemale.equals("")) {           
            committeesInfo.setTotalFemale(Integer.valueOf(totalFemale.trim()));
        }else{
            committeesInfo.setTotalFemale(null);           
        }



Return Value:
It returns a copy of this string with leading and trailing white space removed, or this string if it has no leading or trailing white space.



Example:
import java.io.*;

public class Test{
   public static void main(String args[]){
      String Str = new String("   Welcome to Tutorialspoint.com   ");

      System.out.print("Return Value :" );
      System.out.println(Str.trim() );
 //System.out.println(Str);   // For This out put is : Return Value :   Welcome to Tutorialspoint.com
   }
}
This produces the following result:

Return Value :Welcome to Tutorialspoint.com
