直接拿compare工具比下算了..
{
public static void main(String[] args)
{
String[][] stu = new String[4][];
stu[0] = new String[6];
for ( int i = 0; i < stu[0].length;i++ )
stu[0][i] = "java" + (i + 1);
stu[1] = new String[3];
for ( int i = 0; i < stu[1].length; i++ )
stu[1][i] = "c++" + (i + 1);
stu[2] = new String[5];
for ( int i = 0; i < stu[2].length; i++ )
stu[2][i] = "J2ME" + (i + 1); //stu[2][i] = "j2me" + (i + 1);
stu[3] = new String[2]; //stu[3] = new String[4];
for ( int i = 0; i < stu[3].length; i++ )
stu[3][i] = "潜入式" + (i + 1); //stu[3][i] = "嵌入式" + (i + 1);
for ( int i = 0; i < stu.length; i++ )
{
switch (i)
{
case 0: System.out.println("java班: ");
break;
case 1: System.out.println("c++班: ");
break;
case 2: System.out.println("J2ME班: ");
break;
case 3: System.out.println("潜入式班: "); //System.out.println("嵌入式班:");
System.out.println(" "); //System.out.print(" ");
}
for ( int j = 0; j < stu[i].length; j++ )
{
System.out.println( stu[i][j] + " "); //System.out.print(stu[i][j] + " ");
} System.out.println();
}
}
}注释部分是不同的,我只找到这些.
