Common Data Transformation in Java)

1.int --> short

Exp: Short callback Var = 0;


Int intvar = 0;


Using VaR = (short) intvar

2. Short --> int



Exp: Short callback Var = 0;


Int intvar = 0;


Intvar = callback var;

3. Int-> string


Exp: int intvar = 1;


String stringvar;


Stringvar = string. valueof (intvar );

4. Float-> string


Exp: Float floatvar = 9.99f;


String stringvar;


Stringvar = string. valueof (floatvar );

5. Double-> string


Exp double doublevar = 99999999.99;


String stringvar;


Stringvar = string. valueof (doublevar );

6. Char-> string


Exp char charvar = 'a ';


String stringvar;


Stringvar = string. valueof (charvar );

7 string-> int, float, long, double


Exp string intstring = "10 ";


String floatstring = "10.1f ";


String longstring = "99999999 ";


String doublestring = "99999999.9 ";

Int I = integer. parseint (intstring );


Float F = integer. parseint (floatstring );


Long Lo = long. parseint (longstring );


Double D = double. parseint (doublestring );

8 string-> byte, short


Exp string S = "0 ";


Byte B = integer. intvalue (s );


Short SH = integer. intvalue (s );

9 string-> char


Exp string S = "ABC ";


Char A = S. charat (0 );


Return character

10 string --> Boolean


String S = "true ";


Boolean flag = Boolean. valueof ("S ");

Long --> int, int --> long

This basic type can be forcibly converted.

Int I = 1;

Long L = (long) I;

Double D = (double) I;

Date (date) ------------> string (character)

Date d = new date ();

String Ss = D. tolocalestring ();

Or

Simpledateformat format = new simpledateformat ("yyyy-mm-dd hh: mm: SS ");

String Ss = format (d );
