14.2 Details of JavaVM extension options

This section explains the details of the JavaVM extension options.

The following Java programs are used as examples in this document:

Java Program example 1

class Example1 {
  public static void main(String[] args) {
    Example1 e1 = new Example1();
    Object obj = new Object();
    e1.method(1, 'Q', obj); // 5th line
  }
 
  void method(int l1, char l2, Object l3) {
    float l4 = 4.0f;
    boolean l5 = true;
    double l6 = Double.MAX_VALUE; // double type maximum value
    Object[] l7 = new Object[10];
 
    try {
     exception-occurred // 15th line
    } catch (Exception e) {
     e.printStackTrace();
    }
  }
}

Java Program example 2

class Example2 {
  public static void main(String[] args) {
    Example2 e2 = new Example2();
    e2.method(); // 4th line
  }
 
  synchronized void method() {
    int l1 = 1;
    float l2 = 2.0f;
    String l3 = "local 3";
    Character l4 = new Character('X');
    Object l5 = new Thread();
    Object[] l6 = new Thread[10];
 
    thread-dump-is-output // 15th line
  }
}

Java Program example 3

class Example3 {
  public static void main(String[] args) {
    Example3 e3 = new Example3();
    e3.method(); // 4th line
  }
 
  void method() {
    String l1 = "local 1";
    StringBuffer l2 = new StringBuffer(l1);
    l2.append(" + local 2");
    Boolean l3 = new Boolean(false);
    Character l4 = new Character('X');
    Long l5 = new Long(Long.MIN_VALUE); // long type minimum value
    Object l6 = new Thread();
    Object[] l7 = new Thread[10];
 
    try {
     exception-occurred // 18th line
    } catch (Exception e) {
     e.printStackTrace();
    }
  }
 
  public String toString() {
    return "I am an Example3 instance.";
  }
}
