If it's not Korean, I want to delete it.

I read the text file in Java and convert it into Korean

If it is not Korean among the converted contents, I want to delete all of them.

I don't know what format I'll receive it, but for example, the following form

String [] regex1 = {"aa","a1","11","ㅁ1","ㅁ","ㅁa"};
        for(int i = 0; i < regex1.length; i++) {
        if(!regex1[i].Matches * [I - ㅎㅏ - has drawbacks - hi] + (".*")) 
            System.out.println(regex1[i]);

Results

When you do it with a single string...

String regex2 = "1g$@!3nasdfe4d212@@5d22";
String removehangul = "";
for (int i = 0; i < regex2.length(); i++) 
    if (Character.getType(regex2.charAt(i)) == 5) 
        System.out.print(regex2.charAt(i));
    else
        removehangul += regex2.charAt(i);
System.out.println("\n"+removehangul);

Results
