Answer 1

Answer:

see explaination for program code

Explanation:

program code below:

class Names{

public static String[] makeNames(String[] array1, String[] array2){

if(array1.length == 0) return array2;

if(array2.length == 0) return array1;

String[] res = new String[array1.length*array2.length];

int k = 0;

for(int i=0;i<array1.length;i++){

for(int j=0;j<array2.length;j++){

res[k++] = array1[i] + " " + array2[j];

}

}

return res;

}

public static String[] makeNames(String[] array1, String[] array2, String[] array3){

return makeNames(makeNames(array1, array2), array3);

}

public static void print(String[] array){

for(String name : array){

System.out.println(name);

}

}

public static void main(String[] args) {

String[] first = {"David", "Mike", "Katie", "Lucy"};

String[] middle = {"A","B", "C", "D", "E"};

String[] last = {};

String[] names = makeNames(first, middle, last);

print(names);

print(names);

}

}
