Java Optional for Null Check Without If Statement: Best Practices & Alternatives

///'To check if the //value// is null without using an if statement, you can use the //Optional// class. Here's an example://n//njava//nreturn Stream.of(LocalAndMunicipalCompanyEnum.values())//n .filter(predicate)//n .findFirst()//n .map(mapper)//n .orElseGet(() -> {//n if (value == null) {//n throw new IllegalArgumentException(///'Value cannot be null///');//n }//n return value;//n });//n//n//nIn this example, the //orElseGet// method is used to provide a fallback value in case the optional value is empty. Inside the //orElseGet// method, a lambda expression is used to check if the //value// is null. If it is null, an //IllegalArgumentException// is thrown. Otherwise, the //value// is returned.//n//nNote that using an if statement is generally more readable and straightforward than using //Optional// in this case. The above solution is only provided as an alternative without using an if statement.///
