why use for each loop in java code example

Example 1: java foreach

List<String> someList = new ArrayList<String>();
// add "monkey", "donkey", "skeleton key" to someList
for (String item : someList) {
    System.out.println(item);
}

Example 2: java for each loop

// definition eine Datenstruktur, hier ein Array mit 9 Werten
int[] array = new int[]{4, 8, 4, 2, 2, 1, 1, 5, 9};

// ForEach Schleife
for( int k: array )
{
	System.out.println("k = "+k);
}
