Coding question to check if string contains some chars?

[hacikho]

Hello I have below program in this program I want to check if string a contains all char in char[] b array, with the example of String a="cash" and char[] b={'c', 'h'}, I have correct result, unfortunately my string and char array will be dynamic, will change during the program and if I have String a="h" and char[] b={'c', 'h'}, my program also gives message "Yes it contains", but this is not true accoding to what I try to accomplish, I want to get "No it does not contain message". Can you guys help me?

package stringcheck;

public class StringCheck 
{
    String a="cash";
    char[] b={'c', 'h'};
    
    public StringCheck()
    {
        
    }
    public static void main(String[] args)
    {
        StringCheck mainClass = new StringCheck();
        mainClass.execute();
    }
    
    public void execute()
    {
        if(containsAny(a,b))
        {
            System.out.print("Yes it contains");
        }
        else
        {
            System.out.print("No it  does not contain");
         }
    }
    public static boolean containsAny(String str, char[] searchChars) {
      if (str == null || str.length() == 0 || searchChars == null || searchChars.length == 0) {
          return false;
      }
      for (int i = 0; i < str.length(); i++) {
          char ch = str.charAt(i);
          for (int j = 0; j < searchChars.length; j++) {
              if (searchChars[j] == ch) {
                  return true;
              }
          }
      }
      return false;
  }
}

What are the conditions for a correct match?

[hacikho]

condition is if (string value contains all character in the char array )
Let me give you more example:
Example A)
String a ="abcdef"
char[] b = {'b', 'e', 'a'}
result should be "Yes it contains"

Example B)
String a="abc"
char[] b = {'b', 'd'}
result should be "No it does not contains"

String method indexOf would be my choice, it searches through a String for a char. If it finds the char it returns the index position if not -1.
Use a for loop to loop through the char array calling the strings indexOf method on each char in the array. If it returns -1 you know it doesn't match.
