请教Java如何将全角字符串转换为半角

Answer 1

public static String toDBC(String input) {
if (null != input) {
char c[] = input.toCharArray();
for (int i = 0; i < c.length; i++) {
if ('\u3000' == c[i]) {
c[i] = ' ';
} else if (c[i] > '\uFF00' && c[i] < '\uFF5F') {
c[i] = (char) (c[i] - 65248);
}
}
String dbc = new String(c);
return dbc;
} else {
return null;
}
}
