Java Variables
406
Variable holds the value during the program execution.
Following is the syntax for declaring a Variable
type identifier;
ex:
int i;
Following is the syntax for Initialization
identifier = value;
ex.
i = 10;
You can do these two things in one line
int i = 10;
Let me show you a program to declare & initialize all primitive data types of Java
public class PrimiteDataTypes {
public static void main(String[] args) {
byte byteVal = 127;
short shortVal = 32767;
int intValue = 2147483647;
long longValue = 9223372036854775807L;
float floatValue = 1.5F;
double doubleVaue = 12.678;
char charValue= 'f';
boolean booleanValue = true;
}
}
