How to Declare Arrays and Print Values using For Loop in Java?

//Array One

int[] arr1 = new int[2];
arr1[0]= 10;
arr1[1]= 15;

// System.out.println(arr1[1]);

//Array two
int arr []= {1,2,3,4,5};

// System.out.println(arr[1]);

// For Loop

for ( int i = 0; i< arr.length;i++)
{
// System.out.println(arr[i]);
}

for ( int a = 0; a< arr1.length;a++)
{
// System.out.println(arr1[a]);
}

//Enhanced For Loop
for (int d: arr1)
{
// System.out.println(d);
}
