Java Arrays - For and ForEach Loop - Single And Multi Dimensional Arrays

public class Arrays {

 public static void main(String[] args) {
  String[] alphabet = {"a", "b", "c", "d", "e", "f", "g"};
  
  // With for loop
  
  System.out.println("Old fashioned way");
  int size = alphabet.length;
  
  for(int i=0; i< size; i++){
   System.out.print(alphabet[i] + " ");
  }

  // With for-each loop
  System.out.println("\n\nWith For-Each Loop");
  
  for(String letter : alphabet){
   System.out.print(letter + " ");
  }
 }

}

Here is the output:

Old fashioned way
a b c d e f g 

With For-Each Loop
a b c d e f g 

Here with multi dimensional array example

public class Arrays {
      public static void main(String[] args) {
       // Double Arrays
  String[][] users = {
    {"Jon", "Snow", "js@test.com","78965412"},
    {"Dany", "Targeryan", "dt@test.com", "45632101"},
    {"Arya", "Stark", "as@test.com", "12304569"}
   };
  
  int numOfUsers = users.length;
  int numOfFields = users[0].length;
  
  // With old fashioned way
  System.out.println("\n\nWith old Fashoned Way");
  for(int i=0; i< numOfUsers; i++){
   for(int j=0; j< numOfFields; j++){
    System.out.print(users[i][j] + " ");
   }
   System.out.println();
  }
  
  // Little More Intelligent Way
  System.out.println("\n\nLittle More Intelligent Way");
  for(int i=0; i< numOfUsers; i++){
   String name= users[i][0];
   String lastname = users[i][1];
   String mail = users[i][2];
   String phone = users[i][3];
   System.out.println(name+ " " + lastname+ " " + mail + " " + phone);
  }
  
  // With ForEach Loop
  System.out.println("\n\nWith ForEach Loop");
  for(String[] user: users){
   for(String us: user){
    System.out.print(us + " ");
   }
   System.out.println();
  }
 }

}

Here is the output:
