java字符串与字符数组相互转换

1.字符串转换为字符数组

String msgs = "fb311565682284212010190733000000010001a935c0";
char msd[] = msgs.toCharArray();

2.字符数组转换为字符串

(1)

char[] upperLetterChar = {'A','B','C'};
String str = new String(upperLetterChar);

(2)

char[] upperLetterChar = {'A','B','C'};
String str = String.valueOf(upperLetterChar);
