### Question:
ChineseTrans { public static String toFullWidth(String input) { char[] c = input.toCharArray(); for (int i = 0; i< c.length; i++) { c[i]= toFullWidth(c[i]); } return new String(c); } ChineseTrans(); void ensureST(); String normalizeCAP(String input,boolean b); String normalize(String input); String toTrad(String str); String toSimp(String str); static String toFullWidth(String input); static char toFullWidth(char c); static String toHalfWidth(String input); static void toHalfWidthFile(String infile, String outfile); static void toHalfWidthDir(String path,String suffix);  }### Answer:
@Test public void testToFullWidth() { String str; str = "http: str = tc.toFullWidth(str); System.out.println(str); }
