Java在回调中将字符串变量作为函数传递

public interface Callback {
    void onCallback(String result);
}

public class Main {
    public static void main(String[] args) {
        performAsyncOperation(new Callback() {
            @Override
            public void onCallback(String result) {
                System.out.println("Received result: " + result);
            }
        });
    }
    
    public static void performAsyncOperation(Callback callback) {
        // 模拟异步操作
        new Thread(() -> {
            // 执行异步操作
            String result = "Hello, World!";
            
            // 调用回调方法传递结果
            callback.onCallback(result);
        }).start();
    }
}
