Answer:
first:
public class FinalReverseWithoutUsingStringMethods {
public static void main(String[] args) {
// TODO Auto-generated method stub
String str = "Automation";
StringBuilder str2 = new StringBuilder();
str2.append(str);
str2 = str2.reverse(); // used string builder to reverse
System.out.println(str2);
}
}
second:
public class FinalReverseWithoutUsingInbuiltFunction {
public static void main(String[] args) {
String str = "Saket Saurav";
char chars[] = str.toCharArray(); // converted to character array and printed in reverse order
for(int i= chars.length-1; i>=0; i--) {
System.out.print(chars[i]);
}
}
}
third:
public class FinalReverseWithoutUsingInbuiltFunction {
public static void main(String[] args) {
String str = "Saket Saurav";
char chars[] = str.toCharArray(); // converted to character array and printed in reverse order
for(int i= chars.length-1; i>=0; i--) {
System.out.print(chars[i]);
}
}
}
fourth:
public class FinalReverseWithoutUsingInbuiltFunction {
public static void main(String[] args) {
String str = "Saket Saurav";
char chars[] = str.toCharArray(); // converted to character array and printed in reverse order
for(int i= chars.length-1; i>=0; i--) {
System.out.print(chars[i]);
}
}
}
fifth:
public class FinalReverseWithoutUsingInbuiltFunction {
public static void main(String[] args) {
String str = "Saket Saurav";
char chars[] = str.toCharArray(); // converted to character array and printed in reverse order
for(int i= chars.length-1; i>=0; i--) {
System.out.print(chars[i]);
}
}
}
