I've to write code for:
I'd written the code:
public class tables {
public static void main(String[] args) {
//int[][] table = new int[12][12];
String table="";
for(int i=1; i<13; i++){
for(int j=1; j<13; j++){
//table[i-1][j-1] = i*j;
table+=(i*j)+" ";
}
System.out.println(table.trim());
table="";
}
}
}
But the problem is with the output format. I need the output in a matrix like fashion, each number formatted to a width of 4 (the numbers are right-aligned and strip out leading/trailing spaces on each line). I'd tried google but not find any good solution to my problem. Can anybody help me out?
You can use format()
to format your output according to your need..
for(int i=1; i<13; i++){
for(int j=1; j<13; j++){
System.out.format("%5d", i * j);
}
System.out.println(); // To move to the next line.
}
Or, you can also use: -
System.out.print(String.format("%5d", i * j));
in place of System.out.format
..
Here's is the explanation of how %5d
works: -
%d
which is format specifier for integers..5
in %5d
means the total width your output will take.. So, if your value is 5, it will be printed to cover 5 spaces like this: - ****5
%5d
is used to align right.. For aligning left, you can use %-5d
. For a value 5
, this will print your output as: - 5****
