Modifier isProtected(mod) method in Java with Examples

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

Syntax:

public static boolean isProtected(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 protected modifier; false otherwise.

Below programs illustrate isProtected() method:
Program 1:

// Java program to illustrate isProtected() method

import java.lang.reflect.*;

public class GFG {

    // create a String Field
    protected 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 protected or not
        boolean result = Modifier.isProtected(mod);

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

Output:

Mod integer value 4 is protected : true

Program 2:

// Java program to illustrate isProtected()

import java.lang.reflect.*;

public class GFG {

    // create an int Field
    public int numbers;

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

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

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

        // check Modifier is protected or not
        boolean result
            = Modifier.isProtected(mod);

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

Output:

Mod integer value 1 is protected : false
