java.lang.ArrayIndexOutOfBoundsException: length=5; index=5

You need to count from zero so your last field of an array with the length of 5 is 4

Example:

    String examplearray[]=new String [5];
    System.out.println(examplearray.length)
    >>>5//this is the length
    examplearray={"1","2","3","4","5"}//filling the array
    System.out.println(examplearray.length)
    >>>5//still the same length
    System.out.println(examplearray[4])
    >>>"5"//the content of the examplearray[4] field
