A string palindrome program in Java is a string that reads the same forwards and backwards. Creating a program to check if a given string is a palindrome is a common programming exercise. In this program, we aim to determine whether a given string is a palindrome or not. The program takes a string as input from the user or from a predefined string variable. It then compares the characters from both ends of the string, moving towards the center, to check if they are equal.<\/p>\n

What is a String Palindrome?<\/h2>\n

A string is considered to be a palindrome if it remains unaltered whether it is read from left to right or right to left. The next step is to establish whether the string "str"’s reverse string is the same as it is. So let’s look at the string "str."<\/p>\n

Example:<\/strong><\/p>\n

Input : str = \"abba\" \nOutput: Yes\n\nInput : str = \"abcd\"\nOutput: No <\/code><\/pre>\n
Algorithm to Find the String Palindrome in Java:<\/h2>\n
    \n
  • START<\/li>\n
  • Take input from the user or initialize it manually (string).<\/li>\n
  • Check if the length is equal to zero or one\n
      \n
    • Print it is a palindrome.<\/li>\n<\/ul>\n<\/li>\n
    • Check each character in substring from the front and rear; if found, equal\n
        \n
      • Print it is a palindrome<\/li>\n<\/ul>\n<\/li>\n
      • If steps 3 and 4 fail\n
          \n
        • Print it is not Palindrome<\/li>\n<\/ul>\n<\/li>\n
        • END<\/li>\n<\/ul>\n
          Naive Approach:<\/strong> We can determine whether a given string is a palindrome by comparing the original string to its reversed form.
