String -- Reverse
Write a return method that can reverse String
Ex: Reverse("ABCD"); ==> DCBA
USING CORE JAVA
public static String StrReverse(String str) {
String reverse="";
for(int i=str.length()-1; i >= 0; i--)
reverse += str.toCharArray()[i];
return reverse;
}
USING STRING BUFFER/BUILDER
public static String Reverse(String str) {
return new StringBuffer(str).reverse().toString();
}reverse a string
public static String reverse(String orig)
{
char[] s = orig.toCharArray();
int n = s.length;
int halfLength = n / 2;
for (int i=0; i<halfLength; i++)
{
char temp = s[i];
s[i] = s[n-1-i];
s[n-1-i] = temp;
}
return new String(s);
