Lets do the Project

Lets Create the three different Functions  and do the Calculation

when you calculate the Employee Salary there should be the Condition

if the Basic Salary > 50000/= include Tax 0.1 allowance 0.15

if the Basic Salary > 30000/= include Tax 0.05 allowance 0.1

if the Basic Salary > 15000/= include Tax 0.0 allowance 0.05

 public void SalaryCall()
    {
        double bsal,tax,allo,nsal;
        bsal = Double.valueOf(txtbsal.getText()).doubleValue();

        if(bsal > 50000)
        {
            tax = bsal * 0.1;
            allo =  bsal * 0.15;
        }
        else if(bsal > 30000)
        {
            tax = bsal * 0.05;
            allo =  bsal * 0.1;
        }
         else if(bsal > 15000)
        {
            tax = 0.0;
            allo =  bsal * 0.5;
        }
         else 
        {
            tax = 0.0;
            allo =  0.0;
        }
        nsal = bsal + allo - tax;
        
        txttax.setText(String.valueOf(tax));
        txtallow.setText(String.valueOf(allo));
        txttotal.setText(String.valueOf(nsal));
        
        
    }

     public void Clear()
    {
        txtbsal.setText("");
        txttax.setText("");
        txtallow.setText("");
        txttotal.setText("");
        txtbsal.requestFocus();
    
    }
     public void Exit()
    {
       System.exit(0);
    }

After that call the Function inside the button

    private void jButton2ActionPerformed(java.awt.event.ActionEvent evt) {                                         
       
        SalaryCall();
    }                                        

    private void jButton3ActionPerformed(java.awt.event.ActionEvent evt) {                                         

        System.exit(0);
    }                                        

    private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {                                         
       
        Clear();
    }
