I have a globle flag to enable logging / disable logging and a class level flag as well.
This is the code:
public class Utils {
public static volatile boolean GLOBLE_LOG_FLAG = true;
}
public class TestClass {
private static volatile Boolean LOCAL_LOG_FLAG = Utils.GLOBLE_LOG_FLAG;
public void test() {
System.out.println("LOCAL_LOG_FLAG: = " + LOCAL_LOG_FLAG);
Utils.GLOBLE_LOG_FLAG = false;
System.out.println("now LOCAL_LOG_FLAG: = " + LOCAL_LOG_FLAG);
}
}
public static void main(String[] args) {
TestClass class1 = new TestClass();
class1.test();
}
Output:
LOCAL_LOG_FLAG: = true
now LOCAL_LOG_FLAG: = true
Why LOCAL_LOG_FLAG
does not change when i set Utils.GLOBLE_LOG_FLAG = false;
If java is using object reference it should change LOCAL_LOG_FLAG
to false when I assign Utils.GLOBLE_LOG_FLAG = false;
isn't it ? What's my mistake here?
Thanks
