Java中简单提示异常代码的行号，类名等

public class Test1 {

    public static void main(String args[]) {

        System.out.println(getLineInfo());

        getExp();

    }

    public static String getLineInfo() {

        StackTraceElement ste = new Throwable().getStackTrace()[1];

        return ste.getFileName() + ": Line " + ste.getLineNumber();

    }

    public static String getExp(){

        try{

            throw new Exception("Exception Test");

        }catch(Exception e){

            StackTraceElement ste =e.getStackTrace()[0];

            System.out.println(ste.getClassName());

            System.out.println(ste.getFileName());

            System.out.println(ste.getLineNumber());

            System.out.println(ste.getMethodName());

        }

        return null;

    }

}
