# 计算Vega
d_sigma这段代码存在资源未关闭的风险，需要修改来避免`OBL_UNSATISFIED_OBLIGATION_EXCEPTION_EDGE = 0.01
sigma_up = sigma + d_sigma
option_price_up = calculate_delta(S, K, r, sigma`警告。

修改后的代码如下：

public SSLContext loadTwoWayTrust(RestSystemConfigDto restSystemConfigDto) {         
    SSLContext sslContext = null;         
    String keyStoreFile = restSystemConfigDto.getKeyStoreFile();         
   _up, T, N)[1]
    vega = (option_price_up - option_price[0, 0]) / d_sigma
 String keyPass = restSystemConfigDto.getKeyStorePass();         
    String trustKeyStoreFile = restSystemConfigDto.getTrustStoreFile();    return vega

# 输入期权参数并计算Delta、Gamma和Vega
S = 100
K = 100         
    String trustKeyPass = restSystemConfigDto.getTrustStorePass();         
    String keystoreType = restSystemConfigDto.getKeyStore
r = 0.05
sigma = 0.2
T = 1
N = 100

delta = calculate_deltaType();         
    // 判断是否正确配置keystore以及trust keystore信息         
    if (StringUtil.isNotEmpty(keyStoreFile) && StringUtil.isNotEmpty(keyPass) && StringUtil.isNotEmpty(                 
            trustKeyStoreFile) && StringUtil.isNotEmpty(trustKeyPass)) {             
        try ((S, K, r, sigma, T, N)[0]
gamma = calculate_gamma(S, K, r, sigma, T, NFileInputStream trustIns = new FileInputStream(trustKeyStoreFile);
             FileInputStream keyStoreIns = new FileInputStream(keyStoreFile)) {
            KeyStore trustStore = KeyStore.getInstance(keystoreType);                 
            KeyStore keyStore = KeyStore.getInstance(keystoreType);                 
)
vega = calculate_vega(S, K, r, sigma, T, N)

# 输出结果
print("Delta: {:.4            trustStore.load(trustIns, trustKeyPass.toCharArray());                 
            keyStore.load(keyStoreIns, keyPass.toCharArray());                 
           f}".format(delta))
print("Gamma: {:.4f}".format(gamma))
print("Vega: {:.4f}".format(ve sslContext = SSLContexts.custom().loadKeyMaterial(keyStore, keyPass.toCharArray())                         
                    .loadTrustMaterial(trustStore,ga))

在上面的代码中，我们定义了三个函数分别计算Delta、Gamma和Vega。这 new TrustSelfSignedStrategy()).build();
}
catch (Exception ex) {
logger.debug("load keystore or trust keystore file failure.", ex);
sslContext = loadAllTrust();
}
}
else {
些函数的实现基于二叉树模型，使用递归的方式来计算股票价格和期权价格，并 logger.debug("not found keystore or trust keystore.");
sslContext = loadAllTrust();
}
return ssl根据价格变化计算希腊字母。最后，我们输入期权参数并调用这些函数来计算Context;
}

在修改后的代码中，我们使用了`try-with-resources`语句块来声明和初始化`Delta、Gamma和Vega，并输出结果。

需要注意的是，二叉树模型的精度取决于节点数NFileInputStream`，从而避免了资源未关闭的风险。同时，我们也删除了`finally`语句块，因为`try-with-resources`会自动关闭资源，不需要手动关闭。
