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?
   
   

Ajava.util.Arrays.replace (x, 25) ;

Bjava.util.Arrays.insert (x, 25) ; I think This one

Cjava.util.Arrays.fill (x, 25) ;

Djava.util.Arrays.setAll (x, 25) ;

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 determine if the two arrays have the same contents?
   
   

Aboolean b = java.util.Arrays.compare (x, y) ;

Bboolean b = java.util.Arrays.equals (x, y) ;

C)boolean b = java.util.Arrays.check (x, y) ; I say this one

Dboolean b = java.util.Arrays.binaryCompare (x, y) ;

1. 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?
   
   

Ajava.util.Arrays.sort (x, y) ;

Bjava.util.Arrays.binarySort (x, y) ; This one?

Cjava.util.Arrays.order (x, y) ;

D.java.util.Arrays.reorder (x, y) ;

1. 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?
   
   

Aint loc = java.util.Arrays.search (x, 7) ;

Bint loc = java.util.Arrays.binarySearch (x, 7) ;

Cint loc = java.util.Arrays.find (x, 7) ; This one

Dint loc = java.util.Arrays.locate (x, 7) ;

Please let me know if my answers are right or wrong and why!

Thank you so much!!
