c语言中的这个"\x1C\x1D\x1E\x1F"在java中怎么表示出来

/x1C/x1D/x1E/x1F分别对应ASCII码的028,029,030,031四个字符.在C语言中直接用printf("/x1C/x1D/x1E/x1F");就能打印出来,在JAVA中,打印如下:
class Character
{
char i;
}

public class Test
{
public static void main(String[] args)
{
Character c1 = new Character();
Character c2 = new Character();
Character c3 = new Character();
Character c4 = new Character();
c1.i = 28;c2.i = 29;c3.i = 30;c4.i = 31;
System.out.println(c1.i);
System.out.println(c2.i);
System.out.println(c3.i);
System.out.println(c4.i);
}
}
