## StringReplace
|
||
|
|
|
||
|
|
### Instructions
|
||
|
|
|
||
|
|
Create a file `StringReplace.java`.
|
||
|
|
|
||
|
|
Write a function called `StringReplace` that takes in three parameters: `original_string s`, `target`, and `replacement`. The function should replace all occurrences of target in `original_string s` with `replacement` and return the modified string.
|
||
|
|
|
||
|
|
### Expected Functions
|
||
|
|
|
||
|
|
```java
|
||
|
|
public class StringReplace {
|
||
|
|
public static String replace(String s, target, replacement) {
|
||
|
|
// your code here
|
||
|
|
}
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
### Usage
|
||
|
|
|
||
|
|
Here is a possible ExerciseRunner.java to test your function :
|
||
|
|
|
||
|
|
```java
|
||
|
|
public class ExerciseRunner {
|
||
|
|
public static void main(String[] args) {
|
||
|
|
System.out.println(StringContain.replace("javatpoint is a very good website", 'a', 'e'));
|
||
|
|
System.out.println(StringContain.replace("my name is khan my name is java", "is","was"));
|
||
|
|
System.out.println(StringContain.replace("hey i'am java", "I'am","was"));
|
||
|
|
}
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
and its output :
|
||
|
|
|
||
|
|
```shell
|
||
|
|
$ javac *.java -d build
|
||
|
|
$ java -cp build ExerciseRunner
|
||
|
|
