我有一个简单的2D数组正在打印到屏幕上。
我的问题是代码无法正常编译,我做错了什么?
我的非工作代码是:
/* This program initialises two-dimensional arrays.......*/
/* ********************************************************/
public class InitArray4
{
// create and output two-dimensional arrays
public static void main( String[] args )
{
int[][] array1 = { { 1, 2, 3 }, { 4, 5, 6 } };
int[][] array2 = { { 1, 2 }, { 3 }, { 4, 5, 6 } };
System.out.println( "Values in array1 by row are" );
outputArray( array1 ); // displays array1 by row
System.out.println( "\nValues in array2 by row are" );
outputArray( array2 ); // displays array2 by row
} // end main
// output rows and columns of a two-dimensional array
public static void outputArray()
{
// loop through array's rows
for ( int row = 0; row < array.length; row++ )
{
// loop through columns of current row
for ( int column = 0; column < array[ row ].length; column++ )
System.out.printf( "%d ", array[ row ][ column ] );
System.out.println(); // start new line of output
} // end outer for
} // end method outputArray
} // end class InitArray

只需在函数中添加参数
public static void outputArray( int[][] array) {
