Method Detail

arraycopy

public static void arraycopy(char[] src,
                             int srcOffset,
                             char[] dest,
                             int destOffset,
                             int length)

Copies one array to another. Taken from System. Can NOT be used, as it is in package scope.

Parameters:

src - the source array

srcOffset - the offset within source array

dest - the destination array

destOffset - the offset within destination array

length - the number of chars to copy

concat

public static java.lang.String concat(java.lang.String s1,
                                      java.lang.String s2)

Concatenates two Strings without using StringBuffer, to avoid linking StringBuffer and therefore Math library.

Parameters:

s1 - the first string

s2 - the second string

Returns:

the concatenated string. Will be allocated new.

concat

public static java.lang.String concat(java.lang.String s1,
                                      java.lang.String s2,
                                      java.lang.String s3)

Concatenates three Strings without using StringBuffer, to avoid linking StringBuffer and therefore Math library.

Parameters:

s1 - the first string

s2 - the second string

s3 - the third string

Returns:

the concatenated string. Will be allocated new.

convertTime

public static char[] convertTime(int t)

Show elapsed time in an optimal way.

Parameters:

t - the elapsed time

Returns:

the string (as char[]) to display. Always returns 5 characters.
