Assuming - char mychar ; and int myint have been properly declared,
myint = (int) mychar; // converts
This is a feature of Java= to change types, put the type you want to convert into in parenthes before the variable that stores the converted value.
^Will convert your char into an int, but it will be the ascii value.
For example,
mychar = 3;
myint = (int) mychar; //returns 51
To make an accurate one that will not return an error, you can use a try-catch statement
Example
char mychar = '3';
try
{
int myint = (int) mychar;
}catch(NumberFormatException e)
{
//Do whatever you want with it!
}
char a = 'A'; System.out.println((int)a);
in java, char consumes two bytes because it uses unicode instead of ascii. and int takes 4 bytes because 32-bit no will be taken
With an explicit cast, for example (in Java): int i = 0; char c; c = (char) i; Please note that data may be lost in such a conversion; the explicit cast basically tells the compiler "go ahead; I know what I am doing". Without an explicit cast, the compiler won't accept the conversion.
One can convert a string variable to an int variable in Java using the parse integer command. The syntax is int foo = Integer.parseInt("1234"). This line will convert the string in the parenthesis into an integer.
To convert string to int in Java, the easiest way is to simply use the method Integer.parseInt(). For more information how to do this, refer to the integer class documents.
It depends on what you mean by "convert an int to char". If you simply want to cast the value in the int, you can cast it using Java's typecast notation: int i = 97; // 97 is 'a' in ASCII char c = (char) i; // c is now 'a' If you mean transforming the integer 1 into the character '1', you can do it like this: if (i >= 0 && i <= 9) { char c = Character.forDigit(i, 10); .... }
Formally, you cannot do this. A char containing a character value has a different bit configuration than an int. Attempting to convert between the two is non-portable. However, in the ASCII character set, the character '0' has the value 48, or 0x30. If you subtract 48 from the char you will get the int value, but only if the char was one of the digits '0' through '9'. It is better to use the library routines to convert, such as atoi and sscanf, because they will give you predictable, portable results.
The non-class Java data types are primitives: * byte * short * int * long * float * double * boolean * char
char, boolean, byte, short, int, long, double, or float
pick one: int main (void); int main (int argc, char **argv); int main (int argc, char **argv, char **envp);
Only Objects can be used as generic arguments. Primitives Data Types (int, long, char ...) are not objects. But you can use Integer, an Object that wrap the data type int instead.
minimalist: int main (void); standard: int main (int argc, char **argv); unix-only: int main (int argc, char **argv, char **envp);
