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
