Java随机生成n天的体温

疫情期间有一些表格需要填体温数据

public class Test {
    public static void main(String[] args) {
        //随机生成n天体温
        int n = 8;
        double tem[][] = new double[n][3];
        for(int i = 0; i < n;i++){
            for(int j = 0 ;j < tem[i].length;j++){
                tem[i][j] = Math.random()/2;
                tem[i][j]+=36.1;
                System.out.printf("%.1ft",tem[i][j]);
            }
        }
    }
}
