devon_c_miller: Java source consisted of:
public class IntegerParsePerformance {
    public static int parse10(String s)

    }
}

I selected from 'public' to the closing '}' of the method and selected paste (Ctrl-V). The contents of the clipboard was:
public static int parseInt( final String s )
{
    if ( string == null )
        throw new NumberFormatException( "Null string" );

    // Check for a sign.
    int num  = 0;
    int sign = -1;
    final int len  = s.length( );
    final char ch  = s.charAt( 0 );
    if ( ch == '-' )
    {
        if ( len == 1 )
            throw new NumberFormatException( "Missing digits:  " + s );
        sign = 1;
    }
    else
    {
        final int d = ch - '0';
        if ( d < 0 || d > 9 )
            throw new NumberFormatException( "Malformed:  " + s );
        num = -d;
    }

    // Build the number.
    final int max = (sign == -1) ?
        -Integer.MAX_VALUE : Integer.MIN_VALUE;
    final int multmax = max / 10;
    int i = 1;
