How can i use conditional operator in java?

static class Hello{
    private String name;

    public String getName() {
      return name;
    }

    public void setName(String name) {
      this.name = name;
    }
  }

  @GetMapping("/hello")
  @ResponseBody
  public Hello home(@RequestParam(required = false) String name){
    Hello hello = new Hello();

    if(name != null){
      hello.setName(name);
    } else{
      hello.setName("empty");
    }

    // name ? hello.setName(name) : hello.setName("empty");
    // name != null ? hello.setName(name) : hello.setName("empty");

    return hello;
  }

How can I use the commented conditional operation in java?

>Solution :

In javascript, the ternary operator does not have to be used as an expression, whereas in Java, it does, meaning it evaluates to a value, and doesn’t just perform an operation. The reason it is not working in the way you are attempting to use it here is because I’m guessing that setName is a void method, and thus doesn’t evaluate to a value.
Your first attempt (// name ? hello.setName(name) : hello.setName("empty");) also wouldn’t work because name is not a boolean value, and Java does not coerce non-boolean values to booleans in the way that javascript does.
You can use the if/else statement you have to achieve what you want, or do as @Robby Cornelissen suggested: hello.setName(name != null ? name : "empty")
