How can I use the Apex string replace method for replacing all occurrences in the Salesforce apex code?
I am a Salesforce developer and I am currently working on a custom apex class for data processing within my organization’s Salesforce instance. In this particular task, I need to manipulate the strings by replacing certain substrings with new values. How can I use the Apex string replace method for replacing all occurrences of a specific substring within a given string with another in the Salesforce apex code?
n the context of Salesforce, here is how you can use the Apex replace method for replacing all occurrence of a specific substring within a given string with another in Salesforce apex code:-
This example would include a method which would task parameters for the original string, the substring to replace, and the replacement substring:-
Public class StringManipulationExample {
// Method to replace all occurrences of a substring in a string
Public static String replaceSubstring(String originalString, String substringToReplace, String replacementString) {
// Check if the originalString and substringToReplace are not null or empty
If (String.isNotBlank(originalString) && String.isNotBlank(substringToReplace)) {
// Replace all occurrences of substringToReplace with replacementString
Return originalString.replace(substringToReplace, replacementString);
} else {
// Handle null or empty input strings
If (String.isBlank(originalString)) {
System.debug(‘Error: Original string is null or empty.’);
}
If (String.isBlank(substringToReplace)) {
System.debug(‘Error: Substring to replace is null or empty.’);
}
// Return originalString if either originalString or substringToReplace is null or empty
Return originalString;
}
}
// Example usage in a test method
Public static void testReplaceMethod() {
// Original string
String originalString = ‘This is a sample string with some sample text.’;
// Substring to replace
String substringToReplace = ‘sample’;
// Replacement string
String replacementString = ‘example’;
// Call the replaceSubstring method to replace all occurrences
String modifiedString = replaceSubstring(originalString, substringToReplace, replacementString);
// Print the modified string to debug logs
System.debug(‘Modified String: ‘ + modifiedString);
// Output: ‘This is a example string with some example text.’

If you’re looking to replace all occurrences of a substring in Salesforce Apex, the String.replace() or String.replaceAll() methods can help! Let’s break it down:
1. Using replace() (Replaces First Occurrence Only)
The replace() method only replaces the first occurrence of the specified substring.
String text = 'Hello Apex! Apex is fun!';
text = text.replace('Apex', 'Salesforce');
System.debug(text); // Output: "Hello Salesforce! Apex is fun!"
Notice how only the first "Apex" was replaced? That’s because replace() doesn’t target all instances.
2. Using replaceAll() (Replaces All Occurrences)
If you need to replace all instances of a word or phrase, replaceAll() is your go-to method.
String text = 'Hello Apex! Apex is fun!';
text = text.replaceAll('Apex', 'Salesforce');
System.debug(text); // Output: "Hello Salesforce! Salesforce is fun!"
Now, every occurrence of "Apex" is replaced with "Salesforce"
