Question

Guys I’m a bit new in using java and i’m trying to write a program that will check the 2d array if it contains the value of 1d array.The second array is like a list of numbers and it will check the first array if they match.

array1[6]= {"a","b","c","d","e","f"}
array2[1][4]={{"a","b","c","d"}{"d","e","f","g"}}
array2[0]= rowcomplete ; // because it contain all the value a,b,c,d
array2[1]= incomplete; // because it only match d,e,f but not g

This is my code:

String array1[] = {"a","b","c","d","e","f"};
String array2[][] = {{"a","b","c","d"}, {"d","e","f","g"}};

for (int 2row = 0; 2row < array2.length; 2row++) {
  for (int 2column = 0;2column< array2[2row].length;2column++) {    
    for(int 1row=0; 1row < array1[1row].length();1row++) {
      if (array2[2row][2column].equals(array1[1row])) {
        System.out.println("complete"); 
      }
      else{

      }
    }
  }
}

An easy way to do that would be to use the Arrays class to transform your arrays into a List and the use the containsAll method, like this:

  String array1 []={"a","b","c","d","e","f"};
  String array2 [][] ={{"a","b","c","d"},{"d","e","f","g"}};

  List<String> array1AsList = Arrays.asList(array1);

  for (int i = 0; i < array2.length; i++) {
      List<String> array2rowAsList = Arrays.asList(array2[i]);

      if(array1AsList.containsAll(array2rowAsList)){
          System.out.println("row " + i + " is complete");
      }
  }
