"Variable is already assigned to this value" in the init() method of Particle class Bug

[weezard]

Arrange:

• Configuring the environment (with for example Gradle v3.3).
• Importing the junit .jar files, so we can run junit test cases.

Act:

• Making an instance of Particle Class
• Store this instance in a variable
• Call the init() method on this variable, with the following params: int type, Vector2 position, Vector2 velocity, float lifespan, int numFrames and float delay.

Assert:

• A new particle instance will be created after the call of the init() method.

Excepting:

• No unnecessary line of codes run in the method.

Actually:

• There is an if statement that check, if the anim variable is null and if yes, then assign this variable a null, but the variable already has the value of null, so the if statement is unnecessary in the init() method.

Possible solution:

• Delete the 81 line of the Particle Class, since the anim variable has been already assigned to this value.
