Type Casting in Java

//Integer code1
public class CastExample
{
public static void main(String arg[])
{
String s=”27”;
int i=Integer.parseInt(s);
System.out.println(i);
Float f=99.7f;
int i1=Integer.parseInt(f);
}
}

//Integer code2
public class CastExample
{
public static void main(String arg[])
{
String s=”27”;
int i=(int)s;
System.out.println(i);
}
}


//Integer to String
int a=97;
String s=Integer.toString(a);

(or)
String s=””+a;


//Double to String
String s=Double.toString(doublevalue);

//Long to String
String s=Long.toString(longvalue);

//Float to String
String s=Float.toString(floatvalue);

//String to Integer
String s=”7”;
int i=Integer.valueOf(s).intValue();

(or)
int i = Integer.parseInt(s);

//String to Double
double a=Double.valueOf(s).doubleValue();

//String to Long
long lng=Long.valueOf(s).longValue();

(or)
long lng=Long.parseLong(s);

//String to Float
float f=Float.valueOf(s).floatValue();

//Character to Integer
char c=’9’;
int i=(int)c;

//String to Character
String s=”welcome”;
char c=(char)s;
