java loop through arraylist

ArrayList<String> namesList = new ArrayList<String>(Arrays.asList( "alex", "brian", "charles") );
         
for(String name : namesList)
{
    System.out.println(name);
}

java arraylist loop

      for (int counter = 0; counter < arrlist.size(); counter++) { 		      
          System.out.println(arrlist.get(counter)); 		
      }

iterate through an arraylist java

// will iterate through each index of the array list
// using the size of the array list as the max.
// (the last index is the size of the array list - 1)

for (int i = 0; i < myArrayList.size(); i++) {
  
  System.out.println(myArrayList.get(i));
  // will print each index as it loops
}  

java arraylist loop

    List<String> contain = new ArrayList<String>();
    contain.add("HPDH-1,001, Check-out date: 7/7/7");
    contain.add("JTI-1,001, Check-out date: 7/7/7");
    String code = "JTI-1 ";
    for (int i = 0; i < contain.size(); i++) {
        if (contain.get(i).contains(code.trim())) {<---Use trim it is possible that code may have extra space
            System.out.println(contain.get(i));
        }
    }

iterate Through ArrayList Java

import java.util.ArrayList;

class Main {
  public static void main(String[] args) {
    ArrayList<String> animals = new ArrayList<>();

    // add elements in the arraylist
    animals.add("Peacock");
    animals.add("Markhor");
    animals.add("Cow");
    System.out.println("ArrayList: " + animals +"
");

// iterate using for-each loop
    System.out.println("Accessing individual elements:  
");
    for (String language : animals) {
      System.out.print(language);
      System.out.print("
");
    }
  }
}
