for 循环中的 boolean return 语句和 if 语句在 java 中总是返回 false

Question

I am trying to return a boolean output from the function "checkUser" and then to print an output for that. But for every run, it is always returning 'false' even though the conditions are correct. I have used an object to save the boolean result because the return statement is not working inside the 'if'. Also, I am getting the prompt- 'method breakpoint' in 'getCheck()' function. Is there any thing wrong I am doing?

import java.util.Scanner;
class myclass {

    public static void main(String[] args) {
        Scanner sc=new Scanner(System.in);
        Bank[] bk=new Bank[4];
        System.out.println("Enter the Name, Age and the Acc No. of 3 users : ");
        for(int i=0; i<3; i++) {
        //System.out.print("Enter the Name : ");
        String name=sc.next();
        //System.out.print("Enter the age : ");
        int age=sc.nextInt();
        //System.out.print("Enter the Account Number : ");
        int acc_no=sc.nextInt();
        bk[i]=new Bank(name, age, acc_no);
        }
        System.out.println("Enter the Account no to validate a user : ");
        int acc_chk=sc.nextInt();
        
        // method calling
        boolean c=checkUser(bk, acc_chk);
        
        // Outputs
        if(c)
        System.out.println("The user account exits!");
    else
        System.out.println("The user account does not exit!");


}
    // method to check the authenticity of the user
    public static boolean checkUser(Bank[] obj, int ac_no) {

        //boolean ch;
        int j=0;
        for(int i=0; i<3; i++) {
            if(ac_no==obj[i].getAcc()) {
                obj[i].setCheck(true);
                j=i;
            }

        }
        return obj[j].getCheck();
        }
        

    

}
class Bank{
    String name;
    int age;
    int acc;
    String type;
    boolean check;
    
    public Bank(String s, int a, int b) {
        
    }
    public void setName(String s) {this.name=s;}
    public void setAge(int a){this.age=a;}
    public void setAcc(int b){this.acc=b;}
    public void setType(String t) {this.type=t;}
    public void setCheck(boolean ch){this.check=ch;}
    
    public String getName() {return name;}
    public int getAge() {return age;}
    public int getAcc() {return acc;}
    public String getType() {return type;}
    public boolean getCheck() {return check;}
}

Thanks for helping me, everything was right and was working perfectly fine except the constructor Bank . It was not calling the setters so values were not stored in any variable and that's why boolean variable had the default value false which was returned by the function checkUser . Thanks @FedericoklezCulloca, I tried to print the intermediate values but nothing was printing so when I went to check the constructor I found the fault.

public Bank(String s, int a, int b) {
            this.setName(s);
            this.setAge(a);
            this.setAcc(b);
            
        }
