repeat

public static final java.lang.String repeat(char ch,

                                            int min)

Creates a string of arbitrary length by repeating just one character.

Parameters:

ch - The character to use for the string.

len - The length (in characters) of the string to be created. A negative value will be treated as a 0.

min - The minimum length (in characters) of the string to be created. This may seem odd since length is specified, but it is useful sometimes when an expression with unknown value is provided for the length.

Returns:

a string composed only of spaces

repeat

public static final java.lang.String repeat(char ch,
                                            int len)

Creates a string of arbitrary length by repeating just one character.

Parameters:

ch - The character to use for the string.

len - The length (in characters) of the string to be created. A non-positive value is be treated as a 1.
