java求个人所得税，代码的数学逻辑有问题

Question

import java.util.Scanner ;
public class tax{
public static void main(String[ ] args){
Scanner in = new Scanner(System.in);
int t=in.nextInt( );
int ans;
if(t<=60000){
System.out.println("0");}
else if(t>60000){
if((t-60000)<=36000){
ans=(int)((t-60000)0.03);
System.out.printf("%d",ans);}
else if((36000<(t-60000)) && ((t-60000)<=144000)){
ans=(int)((t-36000)0.1+360000.03);
System.out.printf("%d",ans);}
else if((144000<(t-60000)) && ((t-60000)<=300000)){
ans=(int)((t-144000)0.2+360000.03+1080000.1);
System.out.printf("%d",ans);}
else if((300000<(t-60000)) && ((t-60000)<=420000)){
ans=(int)((t-300000)0.25+360000.03+1080000.1+1560000.2);
System.out.printf("%d",ans);}
else if((420000<(t-60000)) && ((t-60000)<=660000)){
ans=(int)((t-420000)0.3+3600000.03+1080000.1+1560000.2+1200000.25);
System.out.printf("%d",ans);}
else if((660000<(t-60000)) && ((t-60000)<=960000)){
ans=(int)((t-660000)0.35+3600000.03+1080000.1+1560000.2+1200000.25+2400000.3);
System.out.printf("%d",ans);}
else if((t-60000)<960000){
ans=(int)((t-960000)0.45+3600000.03+1080000.1+1560000.2+1200000.25+2400000.3+3000000.35);
System.out.printf("%d",ans);}
} } }
以上为代码

Answer 1

年收入120000的时候：
ans=(int)((t-36000)*0.1+(360000)*03);
这个地方错了，除了要减去36000，还需要减去之前免税的60000，在乘以系数0.1
下面同理
