Java various types of conversion between __java

Integer to String:

int i = 42;

String str = integer.tostring (i);

Or

String str = "" + I

Double to String:

String str = double.tostring (i);

Long to String:

String str = long.tostring (l);

float to String:

String str = float.tstring (f);

String to Integer:

str = "25";

int i = integer.valueof (str). Intvalue ();

Or

int i = Integer.parseint (str);

String to Double:

Double d = double.valueof (str). Doublevalue ();

String to Long:

Long L = long.valueof (str). Longvalue ();

Or

Long L = Long.parselong (str);

String to float:

Float f = float.valueof (str). Floatvalue ();

Decimal to binary:

int i = 42;

String bin = integer.tobinarystring (i);

Decimal to hexadecimal:

int i = 42;

String hexstr = integer.tostring (i, 16);

Or

String hexstr = integer.tohexstring (i);

or (with leading zeroes and uppercase)

public class Hex {

public static void Main (String args[]) {

int i = 42;

System.out.print

(Integer.tohexstring (0x10000 | i). SUBSTRING (1). toUpperCase ());

}

}

Hexadecimal (String) to Integer:

int i = integer.valueof ("B8da3"). Intvalue ();

Or

ASCII code to String

int i = 64;

String Achar = new Character ((Char) i). ToString ();

Integer to ASCII code (byte)

char c = ' A ';

int i = (int) c; i = = DECIMAL

To extract Ascii codes from a String

String test = "ABCD";

for (int i = 0; i < test.length (); ++i) {

char C = Test.charat (i);

int j = (int) c;

System.out.println (j);

}

Integer to Boolean

b = (i!= 0);

Boolean to Integer

i = (b)? 1:0;
