java去除下划线并首字母大写

(将如TEST_TB_KKK_LLLL 转换为 testTbKkkLlll)

public static Map zh(Map map) {

HashMap newMap = new HashMap(); for (Entry entry : map.entrySet()) { String key = entry.getKey();

String value = (String) entry.getValue(); String newKey = key.toLowerCase(); StringBuffer sbf = new StringBuffer(); if (newKey.contains(\"_\")) {

// 按下划线来切割字符串为数组 String[] split = newKey.split(\"_\"); // 循环数组操作其中的字符串

for (int i = 0, index = split.length; i < index; i++){ char[] ch = split[i].toCharArray(); if(i>0){

ch[0] = (char) (ch[0] - 32); }

// 添加到字符串缓冲区 sbf.append(ch); } }else{

sbf.append(newKey); }

newMap.put(sbf.toString(), value); }

return newMap; }
