Parameterize call to method name

Question

I've a below class

public class OtherString {

    private String underlyingString;

    public OtherString(String inp) {
        this.underlyingString = inp;
    }

    public String checkAplhaNumeric(String underlyingString) {
        
        String pattern= "^[a-zA-Z0-9]*$";
        return this.underlyingString.matches(pattern) ? "Y" : "N";

    }

    public String checkInteger(String underlyingString) {
        
        String pattern= "^[0-9]*$";
        return this.underlyingString.matches(pattern) ? "Y" : "N";

    }

    public String checkString(String underlyingString) {
        
        String pattern= "^[a-zA-Z]*$";
        return this.underlyingString.matches(pattern) ? "Y" : "N";

    }

}

Is there any way I could decide method to be called at run time for OtherString instance ?

For example:

If String methodName = checkInteger; then call otherStringInstance.checkInteger(inp);
