I need some real help here, this is the assignment I am working on

So what I am trying to do is create a menu that will allow the user to either create a new family history, or print out the NewMod2.family that has already been created, however I am lost on where to put my brackets properly and how best to complete this logic.

package fHist2;

import java.util.Scanner;

public class NewMod2 {

private String name = "Lawrence Magee";

private String name2;

private static String family = "1 wife, 1 daughter";

private static String family2;

{}

{

} //method instance created

private void famRecord(String name, String obj, String family) {

this.name = name;

NewMod2.family = family;

}

private boolean isInvalidStr(String name2) {

String str = null;

if (str.isBlank() || str.isEmpty() || str == null){

return true;

return false;

//main method created

public static int main(String[]args) {

public void famRecord2(String name2, String obj, String family2); {

this.name2 = name2;

NewMod2.family2 = family2;

{

Scanner scanner = new Scanner (System.in);

NewMod2 ob = new NewMod2();

Scanner input = new Scanner(System.in);

while(true)

System.out.println("To create new history: Press 1");

System.out.println("for family history of Lawrence: Press 2 ");

int Choice = (input.nextInt());{

switch (Choice) {

case 1:

System.out.println("Enter your name");

String str = (input.nextLine());

}

}

case 2:

System.out.println("this is your immidiate family history");

System.out.println(" Your name: " + ob.name);

System.out.println(" Family Members" + family);
