Java 避免DD异常而不添加return语句

我有这段代码，我必须避免DD异常“最近重新定义了一个变量”。但我也必须避免创建另一个return语句。我不知道怎么做。如果有人能帮助我，那将是非常有帮助的

DD异常代码

public static boolean hasActiveInternetConnection() {
    int returnVal = 1;
    try {
        final Process ping = java.lang.Runtime.getRuntime().exec("ping -c 1 www.google.com");
        returnVal = ping.waitFor();
    } catch (final java.io.IOException | InterruptedException e) {
        Log.e(TAG, e.getMessage());
    }
    return returnVal == 0;
}

双返回异常码

public static boolean hasActiveInternetConnection() {
    try {
        final Process ping = java.lang.Runtime.getRuntime().exec("ping -c 1 www.google.com");
        final int returnVal = ping.waitFor();
        return returnVal == 0;
    } catch (final java.io.IOException | InterruptedException e) {
        Log.e(TAG, e.getMessage());
    }
    return false;
}

谢谢

public boolean isNetworkActive() {
    try {
     Process ping = java.lang.Runtime.getRuntime().exec("ping -c 1 www.google.com");
     return ping.waitFor()==0? true : false;
    } catch (final java.io.IOException | InterruptedException e) {
       return false;
    }

}

顺便说一句，这不是在Android上测试网络连接的方式，这里有一个更有用的方法：

public static boolean checkNetworkStatus(Context context) {

    ConnectivityManager connMgr = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
    android.net.NetworkInfo wifi = connMgr.getNetworkInfo(ConnectivityManager.TYPE_WIFI);
    android.net.NetworkInfo mobile = connMgr.getNetworkInfo(ConnectivityManager.TYPE_MOBILE);


    boolean networkIsMobile = false;
    boolean networkIsWiFi = false;
    if (wifi != null && wifi.isAvailable() && wifi.isConnected()) {
        networkIsWiFi = true;
    }
    if (mobile != null && mobile.isAvailable() && mobile.isConnected()) {
        networkIsMobile = true;
    }


    boolean networkActive = networkIsMobile || networkIsWiFi;

    return networkActive;
} // End of checkNetworkStatus

---

PS：我假设pingFor==0表示网络，pingFor==1表示无网络，如果是另一种情况，请切换它们

对我有效，我非常感谢
