Import the Scanner class: `import java.util.Scanner;`
Create a Scanner object: `Scanner sc = new Scanner(System.in);`
Read a string: `String text = sc.nextLine();`
Read a single word: `String word = sc.next();`
Read an integer: `int num = sc.nextInt();`
Read a double: `double value = sc.nextDouble();`
Read a float: `float f = sc.nextFloat();`
Read a long: `long l = sc.nextLong();`
Read a boolean: `boolean flag = sc.nextBoolean();`
Read a short: `short s = sc.nextShort();`
Read a byte: `byte b = sc.nextByte();`
Read a char: `char ch = sc.next().charAt(0);`
Check for more input: `sc.hasNext()`
Check for more integer input: `sc.hasNextInt()`
Check for more double input: `sc.hasNextDouble()`
Check for more line input: `sc.hasNextLine()`
Close the Scanner when done: `sc.close();`
Use `nextLine()` after numeric input carefully to consume leftover newline
Use `useDelimiter()` to change input separator if needed
Use `skip()` to ignore unwanted input patterns
Use `hasNextX()` before reading to avoid input errors
