System.out.println("{s + b}{s - b}");

// output -> The second element of the array is: 456
String[] arr = {"123", "456", "789"};
System.out.println("The second element of the array is: {arr[1]}");

// output -> wow, fstring in java
public String getTitle(String s) {
    return s;
}
System.out.println("wow, {this.getTitle(\\"fstring\\") in java}");
System.out.println("wow, {this.getTitle(`fstring`) in java}"); // use ` instead of "

// output -> b is 1
int b = 1;
System.out.println("{b == 1 ? `b is 1`: `b not is 1`}");

// output -> hello {`579-333`} world
@FormatString`
public String myTestFunc(int a, int b) {
