int range in java code example
Example 1: random number in range java
(int)(Math.random() * ((max - min) + 1)) + min
Copy
Example 2: all data types in java
Data Type Size Stores
byte 1 byte whole numbers from -128 to 127
short 2 bytes whole numbers from -32,768 to 32,767
int 4 bytes whole numbers from -2,147,483,648 to 2,147,483,647
long 8 bytes whole numbers from -9,223,372,036,854,775,808 to 9,223,372,036,854,775,807
float 4 bytes fractional numbers; sufficient for storing 6 to 7 decimal digits
double 8 bytes fractional numbers; sufficient for storing 15 decimal digits
boolean 1 bit true or false values
char 2 bytes single character/letter or ASCII values
Example 3: java generate random integer in range
import java.util.concurrent.ThreadLocalRandom;
int randomNum = ThreadLocalRandom.current().nextInt(min, max + 1);
Example 4: primitive data types in java
Example 5: int java
boolean result = true;
char capitalC = 'C';
byte b = 100;
short s = 10000;
int i = 100000;
Example 6: java long literal
