C语言中有__LINE__、__FILE__表示行号和文件名称，在Java中可以通过StackTraceElement类实现类似的功能。如：
System.out.println(Thread.currentThread().getStackTrace()[1].getClassName());
System.out.println(Thread.currentThread().getStackTrace()[1].getFileName());
System.out.println(Thread.currentThread().getStackTrace()[1].getMethodName());
System.out.println(Thread.currentThread().getStackTrace()[1].getLineNumber());
System.out.println(new Throwable().getStackTrace()[0].getFileName());
System.out.println(new Throwable().getStackTrace()[0].getLineNumber());
package test;
public class StackTraceElementTest
{
public void methodA() {
methodB();
}
public void methodB() {
StackTraceElement[] stacks = Thread.currentThread().getStackTrace();
for(StackTraceElement s : stacks) {
System.out.println("*******************");
System.out.println("fileName :"+s.getFileName());
System.out.println("methodName:"+s.getMethodName());
System.out.println("lineNumber:"+s.getLineNumber());
System.out.println("["+s+"]");
}
}
public static void main(String[] args)
{
new StackTraceElementTest().methodA();
}
} /* output:
*******************

methodName:getStackTrace
lineNumber:1479
[java.lang.Thread.getStackTrace(Thread.java:1479)]
*******************
