参数:

b - the int value to be written

抛出:

IOException - If an I/O error occurs

write

public void write(int n)
           throws IOException

Writes a int value, will be convert to int string

参数:

n - the int value to be written

IOException - If an I/O error occurs

write

public void write(long l)
           throws IOException

Writes a long value, will be convert to long string

参数:

l - the long value to be written

抛出:

IOException - If an I/O error occurs

write

public void write(float f)
           throws IOException

d - the double-precision floating-point to be written

抛出:

IOException - If an I/O error occurs

write

public void write(String text)
           throws IOException

Compression and escape char sequence - line-break, double-quote or commas should be quoted. - A (double) quote character in a field must be represented by two (double) quote characters.

参数:

text - the string to be written

抛出:

IOException - If an I/O error occurs

write

public void write(char[] chars)
           throws IOException

Compression and escape char sequence - line-break, double-quote or commas should be quoted. - A (double) quote character in a field must be represented by two (double) quote characters.

参数:

chars - the char sequence to be written

抛出:

IOException - If an I/O error occurs

write

public void write(char[] chars,
                  int offset,
