Error This expression is not allowed in this context [message #1076937]

I used the findFirst to search an array.

The code below gives me an error "This expression is not allowed in this context, since to does not cause any side effects."

xArray.findFirst[name.equals("ME")
   gender != 0
   age.equals(20)   
]

But, it works if I do it this way:

xArray.findFirst[gender != 0]

Whats the proper way of using [x != 0] inside the findFirst if there are more than 1 predicate?

xArray.findFirst[name.equals("ME") &&

age.equals(20)
]
