What is length 1 in array?
arr. length returns the length of the array — a number. arr. length - 1 subtracts one from that number, turning it into an index, because (since array indices are zero-based) if the array has 3 elements, the index of the first one is 0 and the index of the last one is 2.
So length (which is 3) minus 1 gives us a 2.How to use length ()- 1 in Java?
length-1 is used only when working with i+1 elements (Finding duplicates,etc.) because there, we don't want the index to go out of bounds.
For an array of length=3 when i=0, "next element exists only for 0 which is 1, and for 1 which is 2.
There exists no next element for the 3rd element".How to find the length of 1d array in Java?
How to find the size of a Java array?
1Declare a variable of type array.
2) Initialize the Java array to a non-null value.
3) Use the length property of the array to get its size.
4) Hold the value of the Java array length in a variable for future use.Array indexes start at 0, unlike normal counting where you typically begin at 1.
So the 1st item is the 0th, the 2nd item is the 1st, the 3rd item is the 4th, etc… So an array with 4 items would only go to the 3rd index.
