Java Collection, ArrayList Exercises: Compare two array lists

Sample Solution:-

Java Code:

import java.util.*;
  public class Exercise13 {
  public static void main(String[] args) {
   ArrayList<String> c1= new ArrayList<String>();
          c1.add("Red");
          c1.add("Green");
          c1.add("Black");
          c1.add("White");
          c1.add("Pink");

          ArrayList<String> c2= new ArrayList<String>();
          c2.add("Red");
          c2.add("Green");
          c2.add("Black");
          c2.add("Pink");

          //Storing the comparison output in ArrayList<String>
          ArrayList<String> c3 = new ArrayList<String>();
          for (String e : c1)
             c3.add(c2.contains(e) ? "Yes" : "No");
          System.out.println(c3);
         
     }
}

Sample Output:

[Yes, Yes, Yes, No, Yes]

Java: Tips of the Day

Choice between Float and Double:

Data type Bytes used Significant figures (decimal)
Float 4 7
Double 8 15

Double is often preferred over float in software where precision is important because of the following reasons:
Most processors take nearly the same amount of processing time to perform operations on Float and Double. Double offers far more precision in the same amount of computation time.
