java convert to roman numerals

To convert an int value to Roman numerals in Java, you can use a series of if statements to check the value of the int and append the corresponding Roman numeral characters to a String variable.

Here is an example of how you can convert an int value to Roman numerals in Java:

int value = 123;
StringBuilder roman = new StringBuilder();
if (value >= 1000) {
    roman.append("M");
    value -= 1000;
}
if (value >= 900) {
    roman.append("CM");
    value -= 900;
}
if (value >= 500) {
    roman.append("D");
    value -= 500;
}
// Add more if statements for the other symbols as needed...
String result = roman.toString();

In this example, we have an int variable called value that contains the value to be converted to Roman numerals. We create a StringBuilder called roman to hold the resulting Roman numeral string, and use a series of if statements to check the value of value and append the corresponding Roman numeral characters to the roman variable. Finally, we use the toString method to convert the roman variable to a String, and assign it to a String variable called result.

You can add more if statements for the other Roman numeral symbols as needed. For example, you can add an if statement to check for the value of 400 (CD), or an if statement to check for the value of 90 (XC).
