My Coding
package SelfLearning;
import java.util.*;
public class CustomerUtil {
     boolean SearchCustomer(List<Customer> listObj , Customer cust )
          Iterator listOfCustomerObj = listObj.iterator();
          Customer cust1 = null ;
          while(listOfCustomerObj.hasNext())
               cust1 = (Customer) listOfCustomerObj.next();
          if(cust1.getFirstName().equalsIgnoreCase(cust.getFirstName()))
               System.out.println("Customer Found");
          if(cust1.getLastName().equalsIgnoreCase(cust.getLastName()))
               System.out.println("Customer Found");     
// I am getting error here , How to fix this error . please let me know is there any another want to rewrite this condition.
          if(cust1.getFirstName()&& cust1.getLastName().equalsIgnoreCase(cust.getFirstName()&& cust.getLastName())
               System.out.println("Customer Found");
          return true ;
}

Below is my coding
{code }
package SelfLearning;
public class Customer {
     String firstName;
     String LastName;
     String MiddleName;
     public Customer() {
     public Customer(String firstName, String lastName, String middleName) {
          super();
          this.firstName = firstName;
          LastName = lastName;
          MiddleName = middleName;
     public String getFirstName() {
          return firstName;
     public void setFirstName(String firstName) {
          this.firstName = firstName;
     public String getLastName() {
          return LastName;
     public void setLastName(String lastName) {
          LastName = lastName;
     public String getMiddleName() {
          return MiddleName;
     public void setMiddleName(String middleName) {
          MiddleName = middleName;
package SelfLearning;
import java.util.*;
public class CustomerUtil {
     boolean SearchCustomer(List<Customer> listObj , Customer cust )
          Iterator listOfCustomerObj = listObj.iterator();
          Customer cust1 = null ;
          while(listOfCustomerObj.hasNext())
               cust1 = (Customer) listOfCustomerObj.next();
          if(cust1.getFirstName().equalsIgnoreCase(cust.getFirstName()))
               System.out.println("Customer Found");
          if(cust1.getLastName().equalsIgnoreCase(cust.getLastName()))
               System.out.println("Customer Found");     
// Here I want to check both first and last name . But Some how I am unable to do it .
          if((cust1.getFirstName()+cust1.getLastName().equalsIgnoreCase(custObj4.getFirstName()+(custObj4.getLastName()))
               System.out.println("Customer Found");
          return true ;
package SelfLearning;
import java.util.ArrayList;
import java.util.List;
public class TestCustomer {

     public static void main(String[] args) {
          Customer custObj1 = new Customer("John" , "Lee ", "jayson");

          Customer custObj3 = new Customer("Bob" , "George ", "K");
          List customerDetails = new ArrayList();
          Customer custObj4 = new Customer();
          custObj4.setFirstName("Kela");
          custObj4.setMiddleName("v");
          customerDetails.add(custObj1);
          customerDetails.add(custObj2);
          customerDetails.add(custObj3);
          CustomerUtil custUtil = new CustomerUtil();
          custUtil.SearchCustomer(customerDetails , custObj4);
