java - 重用代码 - Java

Question

有没有办法通过这些函数中的数组代码重用迭代:

public static double[] ln(double[] z) {
    // returns  an array that consists of the natural logarithm of the values in array z
    int count = 0;

    for (double i : z){
        z[count] = Math.log(i);
        count += 1;
    }
    return z;
}


public static double[] inverse(double[] z) {
    //  returns  an array that consists of the inverse of the values in array z
    int count = 0;

    for (double i : z){
        z[count] = Math.pow(i,-1);
        count += 1;
    }
    return z;
}

是的，使用 http://en.wikipedia.org/wiki/Strategy_pattern但这可能有点矫枉过正。重复迭代和 count++ 看起来还不错。
