Java: How check if two arrays are in same order? -

this question has answer here:

• how compare strings in java? 23 answers

for example, have 2 arrays:

string [] arr1 ={"you", "book"}; string [] arr2 ={"do", "you", "like","book" }; 

i want check if arr1 match arr2 in terms of same order. if arr1 {"book", "you"}, arr1 not match arr2.

alright, think code wrong, anyway:

for (int = 0; i<arr1.length; i++){   (int j=0; j<arr2.length; j++){     if (arr1[i] != arr2[j]){       return null;     }   } } 

but when run it, return null arr1 match arr2.

you can filter elements in array 1 aren't in array 2. result should match array 1.

public static boolean withinandinorder(string[] a, string[] b) {     return arrays.equals(a, arrays.stream(b)                             .parallel()                             .filter(element -> arrays.binarysearch(a, element) >= 0)                             .toarray()); }
