Unicode :- Unicode is universal encoding standard for different languages, Each character or letter, number, or symbol is assigned a unique value that applicable across any programming language.
In the English alphabet, we have the letters A through Z. Meaning only 26 characters are needed in total to represent the entire English alphabet. But other languages need more characters, and often a lot more.
Unicode allows us to represent these languages and the way it works is that by using a combination of the two bytes that a char takes up in memory.
package com.ekumeedhelp;
public class CharType {
public static void main(String[] args) {
char charValue = 'A';
char unicodeValue = '\u0045';
System.out.println(charValue);
System.out.println(unicodeValue);
}
}
Boolean :- A boolean value is either True or False, Yes or No, 1 or 0. In Java terms we have a boolean primitive type and it can be set to two values only. true or false They are actually pretty useful and you will use them a lot when programming
package com.ekumeedhelp;
public class BooleanType {
public static void main(String[] args) {
boolean trueBooleanValue = true;
System.out.println(trueBooleanValue);
boolean falseBooleanValue = false;
System.out.println(falseBooleanValue);
}
}
