[英]how to make a copy-paste script with jcreator?
您能為我提供Java編碼方面的幫助嗎,所以我可以使用命令提示符復制單個文件。
因此,我想從Windows的命令提示符下運行Java文件,例如“ java“我的Java腳本”“我的文件目標”“,並在相同目錄下復制我的”我的文件目標“,而無需替換舊文件。
請幫我?
我帶着這個出來
import java.io.*;
class ReadWrite {
public static void main(String args[]) throws IOException {
FileInputStream fis = new FileInputStream(args[0]);
FileOutputStream fos = new FileOutputStream("output.txt");
int n;
if(args.length != 1)
throw (new RuntimeException("Usage : java ReadWrite <filetoread> <filetowrite>"));
while((n=fis.read()) >= 0)
fos.write(n);
}
}
但是文件的副本名為output.txt,如果我想選擇自己的輸出名稱,你們可以幫助我進行編碼嗎? 如果我在命令提示符下鍵入“ java ReadWrite input.txt(這是我想要的輸出名稱)”
這里真的需要幫助...
import java.util.Scanner;
public class program_23{ // start of class
public static void main(String []args){ // start of main function.
Scanner input = new Scanner (System.in);
// decleration ang initialization of variables
String name = " ";
int age = 0;
int no_of_hour_work = 0;
double daily_rate = 0.0;
// get user input
System.out.print("Employee Name: ");
name = input.nextLine();
System.out.print("Employee Age: ");
age = input.nextInt();
System.out.print("No of hour(s) work: ");
no_of_hour_work = input.nextInt();
// compute for daily rate
daily_rate = no_of_hour_work * 95.75;
// display the daily rate
System.out.print("Dialy rate:"+ daily_rate);
}// end of main
}// end of class
偽代碼:
input = open input stream for file1
output = open output stream for file 2
while (input.read() has more bytes):
write byte to output stream
close(input, output)
