Why don't you try doing it first? This isn't a code writing service. — Lee, May 26 '16 at 08:48

You can do the following: 1. @Override the toString() method in your Car class in order to define how a car is displayed. 2. Use Arrays.toString(a) to print the array of Cars.

This is your answer use this segmenty to your code,

class CarSearch
{
public static void main (String[] args) throws java.lang.Exception
{
    ArrayList<Car> carList= new ArrayList<Car>();
    carList.add(new Car("sdfguis3edha",10,9));
    carList.add(new Car("gfujuukedha",15,29));
    carList.add(new Car("uou9is3edha",99,98));

System.out.println(carList); //print all details

//search

//Search for licence "gfujuukedha"
boolean found=false;
for(Car c: carList){
    if(c.getLicence().equalsIgnoreCase("gfujuukedha"))
{   System.out.println("found details "+ c);
found=true;
    }
}
if(!found){
    System.out.println("This car is not there");
}
}
}

class Car{
String  licence;
int hours, fee;

Car(String licence, int hours, int fee ){
    this.licence= licence;
    this.hours=hours;
    this.fee = fee;
}

String getLicence(){
    return this.licence;
}

int getHours(){
    return this.hours;
}

int getFee(){
    return this.fee;
}

 public String toString() { 
return "Licence: "+this.licence+" Hours: "+ this.hours+" Fees: "+this.fee+"\n";
 }

 }

How do i search for a string in an array and print all arrays?
