我正在尝试在一列和一行中创建以下数字的表示。
为什么我的第二个阵列没有被完全打印出来?
另外,数字不是以行列方式打印的。这是为什么?
public class MultidimensionalArrays
{
public static void main(String[] args)
{
//initializes rows and columns
//first box = row, second box = column
int firstarray[][] = {{3, 4, 5, 6,} , {8, 9}};
//System.out.println(firstarray[0][1]) = 9;
//initializes another rows and columns
int secondarray[][] = {{11, 12, 13} , {88} , {100, 200, 300} , {33, 35, 37}};
//displays the 1st array
System.out.println("this is the 1st array: ");
display(firstarray);
System.out.println();
//displays the 2nd array
System.out.println("this is the 2nd array: ");
display(secondarray);
}
//makes a method to display out the arrays
public static void display(int x[][])
{
//makes a for-loop that prints out the row
for(int row = 0; row < x.length; row++)
{
//makes a for-loop that prints out the column
for(int column = 0; column < x.length; column++)
{
//sysouts the rows & columns
System.out.print(x[row][column] + "\t");
}
}
}
}
错误代码:
this is the 1st array:
3 4 8 9
this is the 2nd array:
11 12 13 Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 3
at MultidimensionalArrays.display(MultidimensionalArrays.java:37)
at MultidimensionalArrays.main(MultidimensionalArrays.java:24)
最佳答案
您的数组不是矩阵,因此列长不等于行长。事实上,不同的行有不同的列数,所以你必须使用每行的单独长度。
尝试:
for(int row = 0; row < x.length; row++)
{
//makes a for-loop that prints out the column
for(int column = 0; column < x[row].length; column++)
{
//sysouts the rows & columns
System.out.print(x[row][column] + "\t");
}
}
