These questions are from java

1. if x and y are both arrays of int values which of the following shows a call to a method of the arrays class that will fill all the elements of the array with the value 25?

a) java. util. arrays. replace (x, 25) ;
b) java. util. arrays. insert (x, 25) ; i think this one
c) java. util. arrays. fill (x, 25) ;
d) java. util. arrays. setall (x, 25) ;

2. if x and y are both arrays of int values, which of the following shows a call to a method of the arrays class that will determine if the two arrays have the same contents?

a) boolean b = java. util. arrays. compare (x, y) ;
b) boolean b = java. util. arrays. equals (x, y) ;
c)boolean b = java. util. arrays. check (x, y) ; i say this one
d) boolean b = java. util. arrays. binarycompare (x, y) ;

3. if x is an array of int values which of the following shows a call to a method of the arrays class that will sort its contents?

a) java. util. arrays. sort (x, y) ;
b) java. util. arrays. binarysort (x, y) ; this one?
c. java. util. arrays. order (x, y) ;
d. java. util. arrays. reorder (x, y) ;

4. if x is a sorted array of int values which of the following shoes a call to a method of the arrays class that will determine if the value 7 exists in the array?

a) int loc = java. util. arrays. search (x, 7) ;
b) int loc = java. util. arrays. binarysearch (x, 7) ;
c) int loc = java. util. arrays. find (x, 7) ; this one
d) int loc = java. util. arrays. locate (x, 7) ;
