Conditional expression

Reports usages of the ternary condition operator and suggests converting them to if/else statements.

Some code standards prohibit the use of the condition operator.

Example:

Object result = (condition) ? foo() : bar();

After the quick-fix is applied:

  Object result;
  if (condition) {
    comp = foo();
  }
  else {
    comp = bar();
  }

Locating this inspection

By ID

Can be used to locate inspection in e.g. Qodana configuration files, where you can quickly enable or disable it, or adjust its settings.

ConditionalExpression

Via Settings dialog

Path to the inspection settings via IntelliJ Platform IDE Settings dialog, when you need to adjust inspection settings directly from your IDE.

Settings or Preferences | Editor | Inspections | Java | Control flow issues

Configure the inspection:

Use the Ignore for simple assignments and returns option to ignore simple assignments and returns and allow the following constructs:

String s = (foo == null) ? "" : foo.toString();

Use the Ignore places where an if statement is not possible option to ignore conditional expressions in contexts in which automatic replacement with an if statement is not possible (for example, when the conditional expression is used as an argument to a super() constructor call).
