java - 检查finally中是否执行了try或执行了catch

Question

是否可以检查移交给finally 的控制权是否来自try 或catch 之一？像这样的东西:

try {
    // Some code
} catch(Exception e) {
    // Some more code
} finally {
    // Check if control came from try or from catch?
}

Answer 1

在 Java 中没有自动化的方法来完成它。您可以创建一个 boolean 标志:

boolean isRaised = false;

try {
    // Some code
}
catch (Exception e) {
    isRaised = true;
}
finally {
    if (isRaised)
        System.out.println("from catch");
    else
        System.out.println("from try");
}
