By Students...Using methods is a common thing in programming. Breaking down big problems into smaller problems will help simplify things. It makes testing easier also because you can test if one method is working and move on. It also makes your code more re-usable.

SolutionThe solution...
To solve this problem we are going to create a skeleton structure. We know that we will have two methods: main & combineNumber. We know that combineNumber will accept two integers and return an integer:
public static void main() { } public static int returnArray( int areaCode, int phoneNumber ) { }
public static void main() { int temp; temp = combineNumber(204, 4881234); // instead of storing in temp you could also just print this directly System.out.println(temp); }
public static int combineNumber( int areaCode, int phoneNumber ) { areaCode = areaCode * 10000000; return (areaCode + phoneNumber); } | ||
