Modifier isStatic(mod) method in Java with Examples

The isStatic(mod) method of java.lang.reflect.Modifier is used to check if the integer argument includes the static modifier or not. If this integer parameter represents static type Modifier then method returns true else false.

Syntax:

public static boolean isStatic(int mod)

Parameters: This method accepts a integer names as mod represents a set of modifiers.

Return: This method returns true if mod includes the static modifier; false otherwise.

Below programs illustrate isStatic() method:
Program 1:

// Java program to illustrate isStatic() method

import java.lang.reflect.*;

public class GFG {

    // create a String Field
    static String string;

    public static void main(String[] args)
        throws NoSuchFieldException,
               SecurityException
    {

        // get Field class object
        Field field
            = GFG.class
                  .getDeclaredField("string");

        // get Modifier Integer value
        int mod = field.getModifiers();

        // check Modifier is static or not
        boolean result = Modifier.isStatic(mod);

        System.out.println("Mod integer value "
                           + mod + " is static : "
                           + result);
    }
}

Output:

Mod integer value 8 is static : true

Program 2:

// Java program to illustrate isStatic()

import java.lang.reflect.*;

public class GFG {

    public static void main(String[] args)
    {

        // get Method class object
        Method[] methods
            = Shape.class.getMethods();

        // get Modifier Integer value
        int mod = methods[0].getModifiers();

        // check Modifier is static or not
        boolean result
            = Modifier.isStatic(mod);

        System.out.println("Mod integer value "
                           + mod + " is static : "
                           + result);
    }

    public static class Shape {

        public static void createShape() {}
    }
}

Output:

Mod integer value 9 is static : true
