')' and '(' expected

Hi,
I am sorry to have to ask this question as it's asked so many times, but I continuously receive ';' and ')' expected errors.
I started using Java just yesterday so the program is really basic but still any help would be greatly appreciated.
Program

import java.util.Scanner;

public class Test1 {
public static void main(String[] args) {
Scanner scans = new Scanner(System.in);
double kg;
double answer;
System.out.println("Kg to Lbs Converter");
System.out.println("Kg to Lbs or Lbs to Kg");
double kgtolbs = 0;
double lbstokg = 0;
if kgtolbs = scans.nextString("Kg to Lbs") {
System.out.println("Kg to Lbs is selected");
}
if lbstokg = scans.nextString("Lbs to Kg") {
System.out.println("Lbs to Kg is selected");
}
}

}

And here is the Error code:

Test1.java:12: '(' expected
if kgtolbs = scans.nextString("Kg to Lbs") {
^
Test1.java:18: illegal start of expression
}
^
Test1.java:17: ')' expected
}
^
3 errors


Thanks in advanced.

Check out the proper syntax for an if statement: The if-then and if-then-else Statements (The Java™ Tutorials > Learning the Java Language > Language Basics)

Hint: Your compiler is telling you exactly what the problem is.

Thanks,
I believe that I did it properly this time, but I know get ';' expected but only one error:

import java.util.Scanner;

public class Test2 {
public static void main(String[] args) {
Scanner scans = new Scanner(System.in);
double kg;
kgtolbsselect = scans.nextString("Kg to Lbs");
lbstokgselect = scans.nextString("Lbs to Kg");
double lbs;
double answer;
System.out.println("Kg to Lbs Converter");
System.out.println("Kg to Lbs or Lbs to Kg");
double kgtolbs = 0;
double lbstokgequation = lbs * 0.4536;
double kgtolbsequation = kg * 2.205;

kgtolbsequation() {

if(kgtolbsselect) {
System.out.println("Kg to Lbs is selected");
}
}
lbstokgequation() {

if(lbstokgselect) {
System.out.println("Lbs to Kg is selected");
}
}
}

}

Here is the error know:

Test2.java:17: ';' expected
kgtolbsequation() {
^

It appears you are defining methods inside of main, these methods also aren't complete.

This line

Code:

---

kgtolbsequation() {

---

is one problem.

You can't have methods within methods. And put the code in [code] tags, right now it's very hard to read. Like this:

Code:

---

method() {
  // code goes here
}
