Java static variable initialization

Java static variable initialization
Static final int NUMBER_OF_MONTHS = 12;
Static final float PI = (float) 22/7;
If you want a static variable to be referenced elsewhere

Public static final int NUMBER_OF_MONTHS = 12;
Public static final float PI = (float) 22/7;

Written in the function

Public class MainClass {

Public static void main (String [] arg ){
Final int FEET_PER_YARD = 3; // Constant values
Final double MM_PER_INCH = 25.4; // that cannot be changed

System. out. println (FEET_PER_YARD );
System. out. println (MM_PER_INCH );
   
  }

}

Static Variable initialization
A static block can be defined in the Java class for static variable initialization. For example:

 

Public class Test {
Public static int _ I;
Static {
_ I = 10;
     }   
}  
Public class Test {public static int _ I; static {_ I = 10 ;}}

Of course, the most common operation to initialize static variables is to directly assign values when declaring variables. For example:

 

Public class Test {
Public static int _ I = 10;
}  
Public class Test {public static int _ I = 10 ;}
