netIncome = keyboard.nextDouble();

if(netIncome <= 370000)

else if((netIncome >= 370001)&&(netIncome <= 990000))

tax = netIncome*0.13-25900;

else if ((netIncome>=990001)&&(netIncome<=1980000))

tax = netIncome*0.21-105100;

else if ((netIncome>=1980001)&&(netIncome<=3720000))

tax = netIncome*0.3-283300;

else if( netIncome >= 3720001 )

   tax = netIncome*0.4-655300;
