Java中参数字符串的压缩和解压缩
我在想办法也无法在Java中解压缩String时遇到麻烦。这是我要学习的基本Java类,因此只需要基本命令,没有什么花哨的地方。它能够输入的目标
C:\>java Compress -c aaaabbbbbcc
在命令提示符下,它将打印a4b5c2
(就像它压缩参数字符串一样)。
另一个目标是输入
C:\>java Compress -d a5b7c4
它将打印aaaaabbbbbbbcccc
(就像它将解压缩参数String一样)。减压是我遇到的问题。这是我的代码,非常感谢我得到的任何帮助。
import java.util.*;public class Compress {
public static void main(String args[]) {
Scanner scan = new Scanner(System.in);
String originalString = scan.nextLine();
int number = scan.nextInt();
if (args[0].equals("-c")) {
System.out.println("compress");
compress(originalString);
}
else if (args[0].equals("-d")) {
System.out.println("decompress");
decompress(originalString);
} else {
System.out.println("Compress program by Kelsey Faram");
System.out.println("usage: java Compress [-c,-d] < inputFile > outputFile");
}
}
public static void compress(String originalString) {
int count = 0;
char comp = originalString.charAt(0);
for (int i = 0; i < originalString.length(); i++) {
originalString.charAt(i);
if (comp == originalString.charAt(i))
count++;
else {
System.out.print(comp + "" + count);
comp = originalString.charAt(i);
count = 1;
}
}
System.out.println(comp + "" + count);
}
public static void decompress(String originalString) {
}
}
回答:
Quick Code for you..
public static void decompress(String originalString){
StringBuffer finalString = new StringBuffer();;
char previouschar = originalString.charAt(0);
for(int i=1; i < originalString.length(); i+=2){
for(int j = 0 ; j< Integer.parseInt(""+originalString.charAt(i));j++) {
finalString.append(previouschar);
}
if(i+1 < originalString.length())
{
previouschar=originalString.charAt(i+1);
}
}
System.out.println(finalString.toString());
}
