While loop is not reading my if statements help please

1 import java.util.Scanner;
2
3 public class DNA {
4
5 public static String GetProteinSeq(String DNA){
6 int BaseCount = 0;
7 int DNALength = DNA.length();
8 String ProteinSeq = "";
9 String BasePairs = "";
10
11 while (BaseCount < DNALength) {
12 BasePairs = DNA.substring(BaseCount, BaseCount+3);
13 //System.out.println(BasePairs); Line shows that its grabbing the base pairs correctly but it does not run it through if statements
14 if (BasePairs=="TAT" || BasePairs =="TTC"){
15 ProteinSeq += 'F';
16 }
17 if (BasePairs=="TTA" || BasePairs=="TTG" || BasePairs==" CTT" || BasePairs=="CTC" || BasePairs=="CTA" || BasePairs=="CTG"){
18 ProteinSeq += "L";
19 }
20 if (BasePairs=="AAT") {
21 ProteinSeq += "J";
22 }
23
24 BaseCount +=3;
25 }

Don't use == for String comparison. Use the equals() method. This advice has been repeated on this forum and elsewhere on the internet, so I'll let you do a search for more detail.
