我想返回2D数组的所有值。如果我使用带String类型的get方法,我怎么能返回它?
public class Data {
private final String[][] table;
public Data(){
table = new String[][] {{"ID", "NAME"},
{"101", "A"},
{"102", "B"},
{"103", "C"},
{"104", "D"},
{"105", "E"}};
}
public String[][] get(){
for (int i = 0; i < table.length; i++) {
for (int j = 0; j < table[i].length; j++) {
table[i][j] = table[i][j];
}
}
return table;
}
public void displayMessage(){
System.out.println(get());
}
}
