Answer:
public boolean equals( String [ ] a, String [ ] b ){
if (a.length == b.length){
for (int i = 0; i < a.length; i++){
if ( ! a [ i ].equals( b [ i ] )) {
return false;
}
}
return true;
}
return false;
}
Explanation:
The above code has been written in Java.
// 1. Method header declaration
// Method name is equals.
// It takes in two arguments which are the two string arrays a and b.
// Since the method returns a true or false, the return type is boolean
public boolean equals( String [ ] a, String [ ] b ){
// 2. Check if the two arrays are of same length
if (a.length == b.length){ // Begin outer if statement
// If they are equal in length,
// write a for loop that cycles through the array.
// The loop should go from zero(0) to one less than
// the length of the array - any of the array.
for (int i = 0; i < a.length; i++){
// At each of the cycle, check if the string values at the index which
// is i, of the two arrays are not equal.
if ( ! a [ i ].equals( b [ i ] )) {
// If they are not equal, exit the loop by returning false.
return false;
}
}
// If for any reason, the for loop finishes execution and does not
// return false, then the two arrays contain the same string values at
// each index. Therefore return true.
return true;
} // End of outer if statement
// If none of the return statements above are executed, return false.
return false;
} // End of method.
Hope this helps!
