java create variable code example

Example 1: declare variables java

/* Depending on what variables you want to declare */
String hello = "hello"; //characters
short one = 12;//shorter integers
int two = 2000; //complete integer up too 32 bits
long number = 2000000; //complete integer up to 64 bits
float decimal = 1.512 //up to 7 decimal digits
double million = 1.387892847395 //up tp 16 decmial digits
Bool condition = true; // true or false
char a = "a"; // unicode character

Example 2: java variables

/*
##	Variable
- Container which holds the value while the Java program is executed. 
- Assigned with a data type. 
- Name of memory location. 

##	There are three types of variables in java: 
1) Local variable 
2) Static (or class) variable 
3) Instance variable
*/

Example 3: java decler variabel

creating first grapper

float simpleInterest; //Declaring float variable
int time = 10, speed = 20; //Declaring and Initializing integer variable
char var = 'h'; // Declaring and Initializing character variable

Example 4: java variable declared

java decleartion 

int a, b, c;         // Declares three ints, a, b, and c.
int a = 10, b = 10;  // Example of initialization
byte B = 22;         // initializes a byte type variable B.
double pi = 3.14159; // declares and assigns a value of PI.
char a = 'a';        // the char variable a iis initialized with value 'a'
