Question

求大神帮我解决下这道java题目？

Answer 1

public static void main(String[] args) {

Scanner in = new Scanner(System.in);

String[][] data = new String[3][2];

for(int i = 0;i < 3;i++)

for(int j = 0;j < 2;j++)

data[i][j] = in.next();

for(int i = 0;i < 3;i++)

{

for(int j = 0;j < 2;j++)

System.out.print(data[i][j] + "  ");

System.out.println();

}

}

Answer 2

String strs[][]=new String[3][2];
strs[0]=new String[2];
strs[1]=new String[2];
strs[2]=new String[2];
Scanner scan=new Scanner(System.in);
for(int i=0;i<strs.length;i++){
for(int j=0;j<strs[i].length;j++){
System.out.println("请输入名字：");
String name=scan.nextLine();
strs[i][j]=name;
}
}
System.out.println("你输入的名字是：");
for(int i=0;i<strs.length;i++){
for(int j=0;j<strs[i].length;j++){

System.out.print(strs[i][j]);
}
System.out.println();
}
放到main方法中执行

Answer 3

String[][] m=new String[3][2];
for(int i=0;i<m.length;i++){
for(int i2=0;i2<m[i].length;i2++){
m[i][i2]="XX";
}
}
for(int i=0;i<m.length;i++)System.out.println(Arrays.toString(m[i]));
