以空格为要求,按要求输出一段字符
假如输入一段luinx命令为单个命令,比如 "rz ",则输出 "^rz *.* "
如果输入是多个命令,如 "rm -rf ",则输出 "^rm .* -rf "
其它判断是多个命令还是单个命令主要以空格来区别(个人认为)
[解决办法]
public String CreateString(String str){
String ss= " ";
for (int i=0;i <str.length();i++){
String s=str.substring(i, i+1);
if (s.equals( " ")){
ss=ss+s;
ss=ss+ "*.* ";
}
else{
ss=ss+s;
}
}
return ss;
}
[解决办法]
String str= "rm -rf ";
str = str.replaceAll( "\\s+ ", "$0.* ");
System.out.println(str);
[解决办法]
public class DateExample {
public static void main(String[] args) {
String str= "rm ";
String ss= " ";
String[] a = str.split( " ");
if(a.length==1){
ss = a[0]+ " *.* ";
}else{
for (int i=0;i <a.length-1;i++){
ss+=a[i]+ ".* ";
}
ss+=a[a.length-1];
}
System.out.println(ss);
}
}
