Write a Java Program to Check Palindrome
PROGRAM: Java Program to Check Palindrome
/* Java Program to Check Palindrome */
1: Java Program to Check Palindrome String
class Main {
public static void main(String[] args) {
String str = “Radar”, reverseStr = “”;
int strLength = str.length();
for (int i = (strLength – 1); i >=0; –i) {
reverseStr = reverseStr + str.charAt(i);
}
if (str.toLowerCase().equals(reverseStr.toLowerCase())) {
System.out.println(str + ” is a Palindrome String.”);
}
else {
System.out.println(str + ” is not a Palindrome String.”);
}
}
}
2: Java Program to Check Palindrome Number
class Main {
public static void main(String[] args) {
int num = 3553, reversedNum = 0, remainder;
// store the number to originalNum
int originalNum = num;
// get the reverse of originalNum
// store it in variable
while (num != 0) {
remainder = num % 10;
reversedNum = reversedNum * 10 + remainder;
num /= 10;
}
// check if reversedNum and originalNum are equal
if (originalNum == reversedNum) {
System.out.println(originalNum + ” is Palindrome.”);
}
else {
System.out.println(originalNum + ” is not Palindrome.”);
}
}
}
