### Question:
Format { public static String i(int v, int width) { return pad(Integer.toString(v), width, true); }  static void tab(StringBuilder sbuff, int tabStop, boolean alwaysOne); static String s(String s, int width); static String pad(String s, int width, boolean rightJustify); static String i(int v, int width); static String l(long v, int width); static String d(double d, int min_sigfig); static String d(double d, int min_sigfig, int width); static String dfrac(double d, int fixed_decimals); static String formatDouble(double d, int min_sigFigs, int fixed_decimals); static String formatByteSize(double size);  }### Answer:
@Test public void testI() { int num = 12345; assertThat(Format.i(num, 2)).isEqualTo("12345"); assertThat(Format.i(num, 3)).isEqualTo("12345"); assertThat(Format.i(num, 4)).isEqualTo("12345"); assertThat(Format.i(num, 5)).isEqualTo("12345"); assertThat(Format.i(num, 6)).isEqualTo(" 12345"); assertThat(Format.i(num, 7)).isEqualTo(" 12345"); }
