99乘法表~~幫忙修改一下

public class sample19{

public static void main(String[] args){
for (int i = 1; i <= 9; i++) {
for (int j = 1; j <= 9; j++) {
System.out.print(i + "X" + j + "=" );
System.out.print(i*j+" ");
}
System.out.println();
}
}
}

import java.io.*;
//import java.util.*;
//類別名稱：java_chk
public class java_chk
{
public static void main(String[] args)
{
PrintStream o=new PrintStream(System.out);
//Scanner in=new Scanner(System.in);
//==START==//
int R=9;
for(int i=0,C=9;i<R*C;i++)
{
o.printf("%d*%d=%2d",(i%C)+1,(i/C)+1,((i%C)+1)*((i/C)+1));
o.printf("%s",((i%C)<(C-1)?", ":"\n"));
}
//==END==//
}
}

for (int i = 1; i <= 9; i++) {
for (int j = 1; j <=9; j++) {
System.out.print(j + "*" + i + "=" + (i * j) + "\t");
}
System.out.println();
}
}

2009-04-13 23:30:38 補充：
提供你另外一種寫法，相同程式運用不同方法，能使邏輯更加清楚
public static void main(String args[]) {
int i = 1;
while (i <= 9) {
int j = 1;
while (j <=9 ) {
System.out.print(i + "*" + j + "=" + (i * j) + "\t");
j++;
}
i++;
System.out.println();
}

}

從打一次不就好了!

自己打比較快吧!
