Idea中提示Statement lambda can be replaced with expression lambda的解决方案

今天在使用Junit5中的assertDoesNotThrow()方法时，idea报出了个警告，

Statement lambda can be replaced with expression lambda less… (Ctrl+F1)

Inspection Info： Reports  lambda expressions with code block bodies when expression-style bodies can be used.

代码如下：

int re =  assertDoesNotThrow(() -> {
            return AssertTestModel.testThrowArithmeticException(2,1);
        });

 解决方案：

int re =  assertDoesNotThrow(()->AssertTestModel.testThrowArithmeticException(2,1));

 由

param -> { return expression; }

 变成

param -> expression
