Trouble with && operator

In the following code the && within the if else statement is giving a syntax error and i'm unsure how to solve it. Can anyone offer a solution?

//Importing scanner
import java.util.Scanner;

public class Credithistory {

    public static void main(String[] args) {            
        //Stating scanner gets its input from console
        Scanner scanner= new Scanner (System.in);           
        //declaring int and boolean         
        int age;
        boolean goodCreditHistory;          
        System.out.println("Please enter your age... ");
        age= scanner.nextInt();         
        System.out.println("Do you have a good credit history (true or flase)?");
        goodCreditHistory= scanner.nextBoolean();           
        if  (age>=18) && ( goodCreditHistory== true){ // <-------------- Error   
            System.out.println("You have got a credit card!");              
        } else 
            System.out.println ("Sorry you are not eligible for a credit card.");
    }       
}

Correct syntax is 

   if  (age>=18 && goodCreditHistory){

}

Remove unnecessary parentheses. And also you need not to write 

goodCreditHistory== true

since it is already a boolean.

This is because of how you put the parentheses. The if statement is composed of two parentheses already, so you have to write you statement as

if ((age>=18) && (goodCreditHistory == true))

instead of

if (age>=18) && (goodCreditHistory == true)

since the second part of your statement (&& (goodCreditHistory == true)) is being parsed as if it was part of the if body.

You may write this statement in a more concise way as

if(age >= 18 && goodCreditHistory)

the extra parentheses are not needed. == true statement is also redundant.

In Java the entire condition for an if statement has to be contained within parentheses, so it should be:

if ((age>=18) && (goodCreditHistory== true)) {

Put both statements in one set of parentheses:

if (age>=18 && goodCreditHistory== true) {
    System.out.println("You have got a credit card!");
}
