1. Regarding character sets and primitive datat types in Java coderanch.comWhat is the excat relation between "char", "int", and "byte" ? how can we relate these three datatypes and UNICODE as well as ASCII ? Is it true that different environments use diffrent character sets? Why ?......whats the character set used by Windows (XP/98/95/NT) ? How does knowledge of character set being used by the environment affects the application being developed ... |
2. primitive 'char' and Unicode. coderanch.comHere's some documentation that I found in the Java API JavaDoc documentation: The basic multilingual plan and supplementary characters. I used to think that UTF-16 meant the 16-bit chars, but I'm learning that UTF means "Unicode Transformational Format". UTF-16, like UTF-8, is a variable-length format. So, should we call the method: codePointAt() instead of charAt(), and call the method codePointCount() instead ... |
3. char primitive coderanch.comA char is 16 bits long. Every character corresponds to a single 16-bit non-negative number. For example, 'A' is 65. The smallest value is 0, and the largest is 65535. You can convert between int and char using a cast. For example int i = (int) 'A'; The variable "i" gets the value 65. Likewise, System.out.println((char) 65); prints "A". Not sure ... |
4. Use of Scanner with primitive type char coderanch.comI need help using the instance of scanner to declare a primitive type char. So far I have declared and instantiated the scanner, and I tested the program using more basic primitive types (i.e. int, double, and short).... System.out.println("Enter an int c") int c = sc.nextInt(); System.out.println("Enter a double d") double d = sc.nextDouble(); System.out.println("Enter a short e") short e = ... |

6. Is "char" big enough? - a question about primitive data type char forums.oracle.comWell, the question suddenly jumped to my mind... As described, the primitive type "char" is a 16-bit unicode, from "\u0000" to "\uffff". [1] But the unicode space should be able to hold more than 100,000 characters. [2] So my question is ... it looks not big enough to hold all these unicode characters into a "char" variable... Reasonable? Please help. Thanks! ... |
