Example 1: java reverse a string
public static String solution(String str) {
return new StringBuffer(str).reverse().toString();
}
public static String solution(String str) {
char[] chars = str.toCharArray();
for(int i = 0, j = str.length() - 1; i < j; i++, j--) {
char ch = chars[i];
chars[i] = chars[j];
chars[j] = ch;
}
return new String(chars);
}
Example 2: reverse a string in java
Solution 1
public static String StrReverse(String str) {
String reverse="";
for(int i=str.length()-1; i >= 0; i--)
reverse += str.toCharArray()[i];
return reverse;
}
Solution 2 (using string buffer)

return new StringBuffer(str).reverse().toString());
}
