我想访问newrepeatedcount类中的类Totalnoofwords
。
我想用
Totalnoofwords
megring的“a”
System.out.println("( "+file1.getName() +" )-" +"Total words counted:"+total);
所以我可以运行两个代码来获取System.out.println("( "+file1.getName() +" )-" +" Total no of words=" + a +"Total repeated words counted:"+total);
以下是我想要的1个输出的片段 (filenameBlog 39.txt) - 单词总数= 83,计算的重复单词总数:4
欢迎任何建议。 我是java的初学者。 以下是我的两个类代码。:)

FilenameFilter filter = new FilenameFilter() {
public boolean accept(File dir, String name) {
return name.endsWith(".txt");
}
};
File folder = new File("E:\\testfolder");
File[] listOfFiles = folder.listFiles(filter);
for (int i = 0; i < listOfFiles.length; i++) {
File file1 = listOfFiles[i];
try {
String content = FileUtils.readFileToString(file1);
} catch (IOException e) {
e.printStackTrace();
}
BufferedReader ins = null;
try {
ins = new BufferedReader (
new InputStreamReader(
new FileInputStream(file1)));
} catch (FileNotFoundException e) {
e.printStackTrace();
}
String line = "", str = "";
int a = 0;
int b = 0;
try {
while ((line = ins.readLine()) != null) {
str += line + " ";
b++;
}
} catch (IOException e) {
e.printStackTrace();
}
StringTokenizer st = new StringTokenizer(str);
while (st.hasMoreTokens()) {
String s = st.nextToken();
a++;
}
System.out.println(" Total no of words=" + a );
}
}
}
newrepeatedcount.java

File[] listOfFiles = folder.listFiles(filter);
for (int i = 0; i < listOfFiles.length; i++) {
File file1 = listOfFiles[i];
try {
String content = FileUtils.readFileToString(file1);
} catch (IOException e) {

try {

}
String st = null;
try {
st = IOUtils.toString(ins);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
//split text to array of words
String[] words=st.split("\\s");
//frequency array
int[] fr=new int[words.length];
//init frequency array
for(int i1=0;i1<fr.length;i1++)
fr[i1]=-1;
//count words frequency
for(int i1=0;i1<words.length;i1++){
for(int j=0;j<words.length;j++){
if(words[i1].equals(words[j]))
{
fr[i1]++;
}
}
}
//clean duplicates
for(int i1=0;i1<words.length;i1++){
for(int j=0;j<words.length;j++){
if(words[i1].equals(words[j]))
{
if(i1!=j) words[i1]="";
}
}
}
//show the output
int total=0;
//System.out.println("Duplicate words:");
for(int i1=0;i1<words.length;i1++){
if(words[i1]!=""){
//System.out.println(words[i1]+"="+fr[i1]);
total+=fr[i1];
}
}
//System.out.println("Total words counted: "+total);
//System.out.println("Total no of repeated words : "+total+" ");
System.out.println("( "+file1.getName() +" )-" +"Total repeated words counted:"+total);
}
}}
我试图将这两个代码放入一个类中
但这两个变量都没有起作用
System.out.println("( "+file1.getName() +" )-" +" Total no of words=" + a +"Total repeated words counted:"+total);
当我没有“a”或“total”运行时(反之亦然)如果我改变了代码(变量)顺序。
任何人都告诉我应该如何获得变量输出? :)
这是我更新的code.below。

无法从其他类访问main函数内的变量。 所以你可以修改Totalnoofwords.java之类的东西。
package Packagename;
public class Totalnoofwords
{
static int a = 1;
public void somename(){
Totalnoofwords A=new Totalnoofwords();
A.a+=5;
System.out.println("a"+A.a);
}
}
,你的newrepeatedcount.java就像
package Packagename;
public class newrepeatedcount {
public static void main(String[] args){
Totalnoofwords B=new Totalnoofwords();
B.somename();
System.out.println("a:"+B.a);
}
}
答案 1 :(得分:1)
package Packagename;
public class newrepeatedcount {
public static void main(String[] args){
Totalnoofwords B=new Totalnoofwords();
B.somename();
System.out.println("a:"+B.a);
}
}

看起来你在同一个软件包中有两种主要方法,我不确定你是否想要这种方式,但这不会起作用,因为你没有重载方法。例如,目前你在一个类中有public static void main(String [] args),如果你改变另一个类来接受一个额外的参数public static void main(String [] args1,String [] args2)。
同样为了访问你的第二堂课,如上所述,你会使用像
这样的东西Totalnoofwords totalNoofWords = new Totalnoofwords();
totalNoofWords.accessSomething();
但这不会起作用,因为你没有构造函数。
