Insert a String into another String in Java
Let’s say we have a string “That’s good!” and within that we need to insert the text “no”. Therefore, the resultant string should be “That’s no good!” −
String str = "That's good!"; String newSub = "no ";
Now, the index where the new sub string will get inserted −
int index = 6;
Insert the new substring now −
StringBuffer resString = new StringBuffer(str); resString.insert(index + 1, newSub);
Let us now see an example to insert a string into another −
Example
import java.lang.*;
public class Main {
public static void main(String[] args) {
String str = "That's good!";
String newSub = "no ";
int index = 6;
System.out.println("Initial String = " + str);
System.out.println("Index where new string will be inserted = " + index);
StringBuffer resString = new StringBuffer(str);
resString.insert(index + 1, newSub);
System.out.println("Resultant String = "+resString.toString());
}
}Output
Initial String = That's good! Index where new string will be inserted = 6 Resultant String = That's no good!
