Length Of the Array

[munnanext]

I am of the opinion that arry elements are indexed from 1 to size of the array, But in some book it is given that array elements are indexed from 0 to (length of the array -1)
Can you tell me which is the correct method?
Appreciate your help

my understanding is that the latter (0-based) is correct. That is, when I initialize an array, the first index is 0.

Its 0.

Be care when looping array values not to go past the end :

int[] arr = new int[5];
//set values somehow

for (int i = 0; i < arr.length; i++) {
  // do something
}
