Javaのローカル変数のデフォルト値は何ですか?

public class LocalVariableTest {
   public void print() {
      int num;
      System.out.println("The number is : " + num);
   }
   public static void main(String args[]) {
      LocalVariableTest obj = new LocalVariableTest();
      obj.print();
   }
}

LocalVariableTest.java:4: error: variable num might not have been initialized
 System.out.println("The number is : " + num);
^
1 error

public class LocalVariableTest {
   public void print() {
      int num = 100;
      System.out.println("The number is : " + num);
   }
   public static void main(String args[]) {
      LocalVariableTest obj = new LocalVariableTest();
      obj.print();
   }
}

The number is : 100
