The isPublic(mod) method of java.lang.reflect.Modifier is used to check if the integer argument includes the public modifier or not. If this integer parameter represents public type Modifier then method returns true else false.
Syntax:
public static boolean isPublic(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 public modifier; false otherwise.
Below programs illustrate isPublic() method:
Program 1:
// Java program to illustrate isPublic() method  import java.lang.reflect.*;  public class GFG {      // create a String Field    public 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 public or not        boolean result = Modifier.isPublic(mod);          System.out.println("Mod integer value "                           + mod + " is public : "                           + result);    }} |
Output:
Mod integer value 1 is public : true
Program 2:
// Java program to illustrate isPublic()  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 public or not        boolean result = Modifier.isPublic(mod);          System.out.println("Mod integer value "                           + mod + " is public : "                           + result);    }} |
Output:
Mod integer value 1 is public : true
