我想读取txt文件前两行的内容,将其存入字符串中并将该字符串传递给我的方法。我不确定在主函数中需要做什么。
以下是我的代码:
public class TestingClass {
Stacked s;// = new Stacked(100);
String Finame;
public TestingClass(Stacked stack) {
//Stacked s = new Stacked(100);
s = stack;
getFileName();
readFileContents();
}
public void readFileContents() {
boolean looping;
DataInputStream in;
String line = "" ;
int j, len;
char ch;
try {
in = new DataInputStream(new FileInputStream(Finame));
len = line.length();
for(j = 0; j<len; j++) {
System.out.println("line["+j+"] = "+line.charAt(j));
}
}
catch(IOException e) {
System.out.println("error " + e);
}
}
public void getFileName() {
Scanner in = new Scanner(System.in);
System.out.println("Enter File Name");
Finame = in.nextLine();
System.out.println("You Entered " + Finame);
}
public static void main(String[] args) {
Stacked st = new Stacked(100);
TestingClass clas = new TestingClass(st);
//String y = new String("(z * j)/(b * 8) ^2");
// clas.test(y);
}
我尝试了以下代码:String x = new String(x.getNewFile()),但我不确定这是否是正确的方法。
