Java --计算百分比

public String getPercent(int x,int total){
String result = "";//接受百分比的值
double x_double = x*1.0;
double tempresult = x/total;

DecimalFormat df1 = new DecimalFormat("0.00%");    //##.00%   百分比格式，后面不足2位的用0补齐
result= df1.format(tempresult);

return result;
}

public String getPercent(int x,int total){
String result = "";//接受百分比的值
double x_double = x*1.0;
double tempresult = x/total;

NumberFormat nf = NumberFormat.getPercentInstance();
nf.setMinimumFractionDigits(2);
result=nf.format(tempresult);

return result;
}
