Junit 5 Test Class Parallel and Test Case Sequential Execution

we needs to run different test case class parallelly but all the test case withing a perticular class must run sequentially. to achive this junit 5 provides another configuraiton property.

package com.example.junit5.sujan;

public class AppleCalculator {
    public int addApple(int appleBag1, int appleBag2) throws InterruptedException {
        return appleBag1 + appleBag2;
    }

    public int subApple(int appleBag1, int appleBag2) throws InterruptedException {
        return appleBag1 - appleBag2;
    }
}

        AppleCalculator appleCalculator = new AppleCalculator();
        assertEquals(2, appleCalculator.addApple(1, 1), "1 apple + 1 apple is 2 apple");
    }

    @Test
