System.exit daemon thread are correct
the second reason seems not correct
public class Test {
void f(){
try{
System.out.println("in a try block");
//throw new Error("error"); // not working
throw new RuntimeException(); // not working
} finally{
System.out.println("finally");
}
}
public static void main(Str
【在 g**e 的大作中提到】

public class Test {
void f(){
try{
System.out.println("in a try block");
//throw new Error("error"); // not working
throw new RuntimeException(); // not working
} finally{
System.out.println("finally");
}
}
public static void main(Str

i shouldn't say "run time error". i actually mean the thread or jvm got
killed or crashed in try/catch block.
finally block will be executed definitely in your code below.

i dont think so
public class Test extends Thread{
@Override
public void run(){
try{
while(true){
System.out.println("in a try block");
Thread.sleep(500);
}
} catch (InterruptedException e) {
e.printStackTrace();
} finally{
System.out.println("finally");

public class Test extends Thread{
@Override
public void run(){
try {
f();
} catch (InterruptedException e) {
e.printStackTrace();
}
}
void f() throws InterruptedException{
try{
while(true){
System.out.println("in a try block");

when machine crashes, or the process is killed.
Q: for a try/catch/finally block when is the finally block not executed?
A: when machine crashes, or the process is killed. A finally is a finally,
very simple, period. What do you think?
