[英]How to include a print statement from another method inside the class
我的問題是如何更改代碼,以使其打印出第一條打印行以及從testBuildCodonMap
方法打印的行? 當前未打印出的打印行是System.out.println(s+"\\t"+codonMap.get(s));
。 我希望將其包含在其他打印語句中。
import java.util.*;
import edu.duke.*;
public class CodonCount {
private HashMap<String,Integer> codonMap;
public CodonCount() {
codonMap = new HashMap<String,Integer>();
}
private void buildCodonMap(int start, String dna) {
//clear out map before building
codonMap.clear();
//This method will build a new map of codons mapped to
//their counts from the string dna with the reading frame
//with the position start (a value of 0, 1, or 2).
for (int index=start; dna.length() - index > 3;index+=3) {
String currentCodon = dna.substring(index,index+3);
if (!codonMap.containsKey(currentCodon)) {
codonMap.put(currentCodon,1);
}
else {
codonMap.put(currentCodon,codonMap.get(currentCodon)+1);
}
}
}
private String getMostCommonCodon() {
//get the codon in a reading frame that has the largest count
//this method assumes the HashMap of codons to counts has already been built
int currentHigh = 0;
String mostCommonCodon = "";
for (String s : codonMap.keySet()) {
int currentCount = codonMap.get(s);
if (currentCount > currentHigh) {
mostCommonCodon = s;
currentHigh = currentCount;
}
}
return mostCommonCodon;
}
private void printCodonCounts(int start, int end) {
//This method prints all the codons in the HashMap along with their
//counts if their count is between start and end, inclusive.
for (String s : codonMap.keySet()) {
if (codonMap.get(s) >= start && codonMap.get(s) <= end) {
System.out.println(s+"\t"+codonMap.get(s));
}
}
}
public void testBuildCodonMap() {
FileResource fileResource = new FileResource();
String dna = fileResource.asString();
dna = dna.toUpperCase();
for (int index=0;index <= 2;index++) {
System.out.println("\nTesting with start position "+index+":\n");
buildCodonMap(index,dna);
String mostCommonCodon = getMostCommonCodon();
System.out.println("Total unique codons found: "+codonMap.size());
System.out.println("\nMost common codon: "+mostCommonCodon
+"\t"+codonMap.get(mostCommonCodon));
printCodonCounts(4,8);
}
}
}
測試樣本文件: CGTTCAAGTTCAA
編輯:我希望輸出看起來像這樣:
以0開頭的閱讀框會產生3個唯一密碼子
最常見的密碼子是TCA,計數為2
1至5(含)之間的密碼子計數為:
CGT 1
三氯乙酸
AGT 1
以1開頭的閱讀框會產生2個唯一的密碼子
最常見的密碼子是帶有2的CAA
1至5(含)之間的密碼子計數為:
CAA 2
GTT 2
以2開頭的閱讀框會產生2個唯一密碼子
最常見的密碼子是TTC,計數為2
1至5(含)之間的密碼子計數為:
TTC 2
AAG 1
我知道了! 行printCodonCounts(4,8);
內部public void testBuildCodonMap()
方法的內部需要更改為printCodonCounts(1,3);
。 這樣就可以執行方法private void printCodonCounts(int start, int end)
內部的print語句。
