Question

Can you change the code into java code?

def reflexive(R):

'''

@param R : set containing homogenous elements

'''

result = []

a = []

y = []

for a1, a2 in R:

if (a1 == a2):

result.append((a1,a2))

y.append(a1)

if (a1 not in a):

a.append(a1) #contains list of a0

if (set(a) == set(y)):

print("Reflexive")

return (result, True)

print("Not Reflexive")

return ([] , False)

Answer 1

import java.util.LinkedList;

public class Main {
    public static boolean isReflexive(LinkedList<Integer> set, LinkedList<int[]> relations) {
        for (Integer element : set) {
            boolean exist = false;
            for (int[] relation : relations) {
                if (relation[0] == element && relation[1] == element) {
                    exist = true;
                    break;
                }
            }
            if (!exist) {
                return false;
            }
        }
        return true;
    }
}
