java iterate list code example

Example 1: java loop through arraylist

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

Example 2: java how to iterate through a arraylist

// Using Classic For Loop
for (int i=0; i<myArrayList.size(); i++) {
    System.out.println(myArrayList.get(i));
}
/*****************************************************/
//Advanced For Loop - ArrayList<String> 
for(String str : myArrayList) {
    System.out.println(str);
}
/*****************************************************/
//Using Iterator
Iterator arrayListIterator = myArrayList.iterator();
while (arrayListIterator.hasNext()) {
    System.out.println(arrayListIterator.next());
}
/*****************************************************/
//ForEach - java 8 - ArrayList<String>
myArrayList.forEach( str -> System.out.println(str));

Example 3: java loop through list

for (E element : list) {
    . . .
}

Example 4: java iterate over list

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

Example 5: iterate list in java

Iterator itr=list.iterator();
while(itr.hasNext)
{
 system.out.println(itr.next); 
}

Example 6: iterate a list using iterator

Iterator<String> crunchifyIterator = crunchifyList.iterator();
        while (crunchifyIterator.hasNext()) {
            System.out.println(crunchifyIterator.next());
        }
