The difference between print, println, and printf

the//print does not wrap and the println has a line wrap feature. Example: Uprint.javaclass uprint{

public static void Main (String arg[])
{
int i,j,k;
for (i=1;i<10;i++)
{
System.out.println ();
for (j=1;j<=i;j++)
{
K=i*j;
System.out.print (i+ "*" +j+ "=" +k+ "");
}
}
}
}

Print , Println , Printf the Difference

Related definitions:

Print: Displays the information in the Command window, and the output cursor is positioned after the last character;

Println : Displays the information in the Command window, and the output cursor is positioned at the beginning of the next line;

Printf: The information is formatted in the Command window, and the output cursor is positioned after the last character , It comes from C language, the function that produces the formatted output (from stdio.h medium);

Related differences:

Print with the Println the only difference :P rint After the output information is not wrapped, Println After the output of the message is automatically wrapped;

Print ("\ n") = Println (""), that System.out.print ("asd\n"); = System.out.println ("ASD");

Note: when copied to the output stream, these sequences cause their related actions to be displayed on devices that have this capability:

\ \ Backslash \a warning \b backspace \f page break \ n line break \ r enter \ t Jump \v vertical Jump-grid \DD D DDD is a 1, 2, or 3-bit octal number. These escape sequences are displayed as bytes with numeric values specified by the octal number.

Print

A.java The text file reads the following code:

Class a{

public static void Main (string[] args) {

System.out.print ("a");

System.out.print ("a");

}

}

The results are as follows:

Aa

Println

B.java The text file reads the following code:

Class b{

public static void Main (string[] args) {

System.out.println ("B");

System.out.println ("B");

}

Type definition:

Character	Input data type	Meaning
D, I	Int	Signed 10 binary number, I is a vintage notation
O	unsigned int	Unsigned 8 binary number
U	unsigned int	Unsigned 10 binary number
X, X	unsigned int	unsigned 16 binary, x abcdef,x with abcdef to represent the number of 10~15
F	Double	Decimal
E, E	Double	Scientific notation represents the number, the case of which is denoted by the case of "E"
G, G	Double	Using the shortest form of the two above, the case is used with%e and%e
C	Char	Converts the input number to the corresponding character
S, s	char *, wchar_t *	String
P	void *	Output pointers in 16 binary form
N	int *	Until this character, the total number of characters output, do not output text
%	Do not enter	The output character "%" itself

Note:%g,%g in the number of decimal places four bits or exponent greater than equal precision with%E,%E, otherwise%f.

C.java The text file reads the following code:

Class c{

public static void Main (string[] args) {

int a = 1;

Double b = 2;

System.out.printf ("%d", a);

System.out.println ();

System.out.printf ("%f", b);

System.out.println ();

System.out.printf ("%.2f", b);
