How can i write java reverse string program in ACM Library

I need a java program which reverse a string with using methods.

For example,

input:-"hellojava"

output:- "avajolleh"

Solution

  • You can directly use 

    String word= "hellojava";

new StringBuilder(word).reverse().toString();

    for one word you need below one. 

    String word= "hello java";

for (String part : word.split(" ")) {
    System.out.print(new StringBuilder(part).reverse().toString());
    System.out.print(" ");
}

    This is supported since java 1.5 ealier versions you should use StringBuffer. And for any Java based project you can use this method. 

    new StringBuffer (word).reverse().toString();
