我希望我的回答能够阅读
1 2 3
Matrix A = 1 2 3
1 2 3
但它的内容是
Matrix A =
1 2 3
1 2 3
1 2 3
有谁能告诉我应该如何进行格式化?
public static void IO(int[][] a, int[][] b)
{
int i;
int j;
System.out.print("Please Enter the Numbers for Matrix A: ");
for(i=0;i<3;i++)
for(j=0;j<3;j++)
a[i][j]=scan.nextInt();
System.out.println();
System.out.print("Please Enter The Numbers for Matrix B: ");
for(i=0;i<3;i++)
for(j=0;j<3;j++)
b[i][j]=scan.nextInt();
System.out.printf("%-1s%n", "Matrix A = ");
for(i=0;i<3;i++)
{
for(j=0;j<3;j++)
{
System.out.printf("%5d", a[i][j]);
}
System.out.println();
}
System.out.printf("%-1s%n", "Matrix B = ");
for(i=0;i<3;i++)
{
for(j=0;j<3;j++)
{
System.out.printf("%5d", b[i][j]);
}
System.out.println();
}
}
我知道这对某些人来说似乎很简单,但我现在只编写了一个学期。非常感谢任何建议!

摆脱:
System.out.printf("%-1s%n", "Matrix A = ");
并将您的循环更改为:
for(i=0;i<3;i++)
{
for(j=0;j<3;j++)
{
if(j == 1)
line_prefix = "Matrix A = ";
else
line_prefix = " ";
System.out.printf("%12.12s%5d", lineprefix, a[i][j]);
}
System.out.println();
}
