Implicit super constructor Object is undefined for default constructor. Must define an explicit constructor

Implicit super constructor Object is undefined for default constructor Must define an explicit constructor

Today while writing test class in eclipse i saw below error:

• This was happening due to my JRE was not set. To find it right click project –> Properties –> Java Build Path –> Click Libraries tab as shown below:

• To set JRE into build path click Add Library…

• Select JRE System Library –> Click Next

• Choose Workspace default JRE or Alternate installed JRE (If you want to install new JRE please use this link : Install new JRE eclipse ) . I choosen Workspace default JRE as below then click finish:

• Now you will see on Libraries tab new JRE system Library is set and active

• Click OK to finish it. This should resolve the issue.

Solution 2:

• Sometime you will see JRE system libraries is already set but still it gives error. To resolve this
• Click project –> Properties –> Java Build Path –> Click Libraries tab –>Select existing JRE or installed new JRE as shown below and click OK to rebuild the project.

• This should resolve the issue.
