Question

java中如何将字符串数组转换成字符串

Answer 1

用substring 截取吧，或者是循环遍历

Answer 2

楼上这个是最好的。
String[] str = {"abc", "bcd", "def"};
StringBuffer sb = new StringBuffer();
for(int i = 0; i < str.length; i++){
sb. append(str[i]);
}
String s = sb.toString();

Answer 3

貌似这样更强大：

/**
* 用分隔符连接字符数组
* @param String[]arr
* @param String sp 如: , $ ##
* @author gaoxc
* @return Striing str
*/
public String implode(String[] arr, String sp){
String tmp = "";
for(String ss:arr) {
tmp += ss+sp;
}
String str = tmp.substring(0, tmp.length()-sp.length());
return str;
}

Answer 4
