In compiler design, the first step is lexical analysis. Here’s how it breaks code into meaning: 🔹 Token – a category (e.g., keyword, identifier, number). 🔹 Lexeme – the actual string in your code that fits a token. 🔹 Pattern – the rule or regular expression that defines which strings belong to a token. Think of it this way: Pattern = rule Lexeme = actual word Token = label Together, they turn raw code into structured input for the compiler. #algorithm #computer #programming #softwaredeveloper

SOLVED: The Tokenizer (aka Lexical Analysis) is a phase within a compiler that converts an input code into an array of tokens.Create a simple tokenizer program that will accept a single line assignment statement written in Java.Examples:1) int x = 1;2) String str = "Hello World",3) double number;The Tokenizer program should then identify the lexemes in your statement and categorize them into their respective tokens. Refer to the symbol table below.Lexemes: int, double, char, StringTokens: - :
