Remove this unused "identification" private field.
Open

  private int identification;
Severity: Major
Found in src/main/java/in/ac/bits/protocolanalyzer/persistence/entity/IPv4Entity.java by sonar-java

If a private field is declared but not used in the program, it can be considered dead code and should therefore be removed. This will improve maintainability because developers will not wonder what the variable is used for.

Note that this rule does not take reflection into account, which means that issues will be raised on private fields that are only accessed using the reflection API.

Noncompliant Code Example

public class MyClass {
  private int foo = 42;

  public int compute(int a) {
    return a * 42;
  }

}

Compliant Solution

public class MyClass {
  public int compute(int a) {
    return a * 42;
  }
}

Exceptions

The Java serialization runtime associates with each serializable class a version number, called serialVersionUID, which is used during deserialization to verify that the sender and receiver of a serialized object have loaded classes for that object that are compatible with respect to serialization.

A serializable class can declare its own serialVersionUID explicitly by declaring a field named serialVersionUID that must be static, final, and of type long. By definition those serialVersionUID fields should not be reported by this rule:

public class MyClass implements java.io.Serializable {
  private static final long serialVersionUID = 42L;
}

Moreover, this rule doesn't raise any issue on annotated fields.

Make the enclosing method "static" or remove this set.

Severity: Critical
Found in src/main/java/in/ac/bits/protocolanalyzer/protocol/Protocol.java by sonar-java

Correctly updating a static field from a non-static method is tricky to get right and could easily lead to bugs if there are multiple class instances and/or multiple threads in play. Ideally, static fields are only updated from synchronized static methods.

This rule raises an issue each time a static field is updated from a non-static method.

public class MyClass {

  private static int count = 0;

  public void doSomething() {
    //...
    count++;  // Noncompliant
  }

Add a private constructor to hide the implicit public one.
Open

public class Security {
Severity: Major
Found in src/main/java/in/ac/bits/protocolanalyzer/utils/Security.java by sonar-java

Utility classes, which are collections of static members, are not meant to be instantiated. Even abstract utility classes, which can be extended, should not have public constructors.

Java adds an implicit public constructor to every class which does not define at least one explicitly. Hence, at least one non-public constructor should be defined.

Noncompliant Code Example

class StringUtils { // Noncompliant

  public static String concatenate(String s1, String s2) {
    return s1 + s2;

Compliant Solution

class StringUtils { // Compliant

When class contains public static void main(String[] args) method it is not considered as utility class and will be ignored by this rule.
