How to check if two given sets are disjoint ? | Java program to check if two sets are disjoint ; Returns true if set1 [ ] and set2 [ ] are disjoint , else false ; Take every element of set1 [ ] and search it in set2 ; If no element of set1 is present in set2 ; Driver program to test above function
public class disjoint1 { boolean aredisjoint ( int set1 [ ] , int set2 [ ] ) { for ( int i = 0 ; i < set1 . length ; i ++ ) { for ( int j = 0 ; j < set2 . length ; j ++ ) { if ( set1 [ i ] == set2 [ j ] ) return false ; } } return true ; } public static void main ( String [ ] args ) { disjoint1 dis = new disjoint1 ( ) ; int set1 [ ] = { 12 , 34 , 11 , 9 , 3 } ; int set2 [ ] = { 7 , 2 , 1 , 5 } ; boolean result = dis . aredisjoint ( set1 , set2 ) ; if ( result ) System . out . println ( " Yes " ) ; else System . out . println ( " No " ) ; } }
