Answer 1

```

public class q
{
public static boolean thereExists(char a, String s)
{
if (s.indexOf(a)>=0)
return true;
else return false;
}

public static String isPermutation(String s, String t)
{
String affirmative = "No";
int charExists = 0;
char [] a = new char[s.length()];
char [] b = new char[t.length()];
for(int i=0; i<s.length() && s.length()==t.length(); i++)
{
a[i]= s.charAt(i);
if (thereExists(a[i], t) && thereExists(b[i], s)==true)
charExists += 1;
if (charExists == s.length())
affirmative = "Yes";
}
return affirmative;
}

public static void main(String [] args)
{
System.out.println(isPermutation(args[0], args[1]));
}
}
