Java入门学习:实现日志方法（记录代码文件名,类名,方法名,行号)

public class LocalLog {

public static void log(String log){
StackTraceElement[] stacks = new Throwable().getStackTrace();
StackTraceElement stack1 = stacks[1];
System.out.println("LOG POINT@"
+ "filename:"+stack1.getFileName()
+ ",classname:"+stack1.getClassName()
+ "methodname:"+stack1.getMethodName()
+ "lineno:"+stack1.getLineNumber());
System.out.println("LOG INFO:"+log);
}

public static void main(String[] args){
LocalLog.log("this is a test!");
}
}

LOG POINT@filename:LocalLog.java,classname:figo.fileParse.LocalLogmethodname:mainlineno:19
LOG INFO:this is a test!
