java实现下面两个算法

这个我做了

有中文翻译吗

    static KeyAndVal out(Byte key, String value) {
        byte[] onesample = value.getBytes();
        value = Normalizer.normalize(value, Normalizer.Form.NFC);
        byte[] depVariables = value.getBytes();

        String outvalue = "", depVarMatrix = "";
        for (int i = 1; i < onesample.length; i++) {
            for (int j = 1; j < onesample.length; j++) {
                outvalue += (onesample[i] * onesample[j]);
                outvalue += ",";
            }
            for (int j = 1; j < depVariables.length; j++) {
                depVarMatrix += (onesample[i] * depVariables[j]);
                depVarMatrix += ",";
            }
            
        }
        outvalue += depVarMatrix;
        return new KeyAndVal("HTH", outvalue);
    }

照着第三张图写了一个我自己都不知道什么意思的方法T~T
