The isTransient(mod) method of java.lang.reflect.Modifier is used to check if the integer argument includes the transient modifier or not. If this integer parameter represents transient type Modifier then method returns true else false.
Syntax:
public static boolean isTransient(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 transient modifier; false otherwise.
Below programs illustrate isTransient() method:
Program 1:
// Java program to illustrate isTransient() method  import java.lang.reflect.*;  public class GFG {      public static transient int number = 1000;      public static void main(String[] args)        throws NoSuchFieldException,               SecurityException    {          // get Field class object        Field field            = GFG                  .class                  .getDeclaredField("number");          // get Modifier Integer value        int mod = field.getModifiers();          // check Modifier is transient or not        boolean result            = Modifier.isTransient(mod);          System.out.println("Mod integer value "                           + mod + " is transient : "                           + result);    }} |
Output:
Mod integer value 137 is transient : true
Program 2:
// Java program to illustrate isTransient()  import java.io.Serializable;import java.lang.reflect.*;  public class GFG {      public static void main(String[] args)        throws NoSuchFieldException,               SecurityException    {          // get Field class object        Field field            = GFGTest                  .class                  .getDeclaredField("password");          // get Modifier Integer value        int mod = field.getModifiers();          // check Modifier is transient or not        boolean result = Modifier.isTransient(mod);          System.out.println("Mod integer value "                           + mod                           + " is transient : "                           + result);    }      // A sample class that uses a transient keyword to    // skip their serialization.    class GFGTest implements Serializable {          // Making password transient for security        private transient String password;          // other code    }} |
Output:
Mod integer value 130 is transient : true
