How to handle a static final field initializer that throws checked exception

在此示例中，我收到错误消息空白的最终字段myClass可能未已初始化:

In this example, I get the error The blank final field myClass may not have been initialized:

private final static MyClass myClass; // <-- error

static {
    try {
        myClass = new MyClass(); // <-- throws exception
        myClass.init();
    } catch (Exception e) {
        // log
    }
}

在该示例中，我收到错误消息 myClass的最后一个字段可能已已经已分配:

In that example, I get the error The final field myClass may already have been assigned:

private final static MyClass myClass;

static {
    try {
        myClass = new MyClass(); // <-- throws exception
        myClass.init();
    } catch (Exception e) {
        myClass = null; // <-- error
        // log
    }
}

对此问题有什么解决办法吗?

In there any solution to that issue?

推荐答案

private final static MyClass myClass;

static {
    MyClass my;
    try {
        my = new MyClass();
        my.init();
    } catch (Exception e) {
        my = null;
        // log
    }
    myClass = my; //only one assignment!
}
