有谁知道如何在Eclipse中为Java分隔控制台文本

Question

Excuse me if I sound ignorant in anyway. This is my first day learning Java and I have a problem. Everytime I run a program. This happens :

Eveytime i run my program, it reads "53308.0of Drew Brees' Pass Yards is533.08Football Fields." I don't know how to put spaces between the number "53308.08" and "of " and also " 533.08" and Football Is this how console text is supposed to be? Can i fix it ?

public class BreesPassingYardsFields { public static void main (String args []) {

double PassYards; // Number of career pass yards Drew Brees has.
double FieldLength; // Number of yards in a football field
double FootballFields; // The amount of football fields Drew Brees has thrown for

PassYards = 53308; // Start with Drew Brees' Pass Yards
FieldLength = 100; // Length of a football field
FootballFields = PassYards / FieldLength; // converts to how many Football Fields Drew Brees has thrown for

System.out.println(PassYards + "of Drew Brees' Pass Yards is" + FootballFields + "Football Fields");

}

}

Answer 1

The simplest way is:

System.out.println(PassYards + " of Drew Brees' Pass Yards is" + FootballFields + " Football Fields");

or you can do something like this:

System.out.format("%f of Drew Brees' Pass Yards is %f Football Fields", PassYards, FootballFields);

%f is format for double nad float, for int you would use %d, you can format the number with some options like %.3f etc. see this http://docs.oracle.com/javase/tutorial/java/data/numberformat.html

Answer 2

System.out.println(PassYards + " of Drew Brees' Pass Yards is " + FootballFields + " Football Fields");

只需在字符串需要的地方添加空格。

Answer 3

你可以有你希望通过填充它们之间你尽可能多的空间" 。

System.out.println(PassYards + " of Drew Brees' Pass Yards is. " + FootballFields + " Football Fields");

Answer 4

将它们像您在文本中那样放置：

System.out.println(PassYards + " of Drew Brees' Pass Yards is " + FootballFields + " Football Fields");
