所以我正在尝试格式化输出
System.out.println("Menu:\nItem#\tItem\t\tPrice\tQuantity");
for(int i=0;i<stock.length;i++){
System.out.println((i+1)+"\t"+stock[i].Description + "\t\t"+stock[i].price + "\t"+stock[i].quantity);
答案 0 :(得分:3)
以下是一个例子:
Object[][] table = new String[4][];
table[0] = new String[] { "Pie", "2.2", "12" };
table[1] = new String[] { "Cracker", "4", "15" };
table[2] = new String[] { "Pop tarts", "1", "4" };
table[3] = new String[] { "Sun Chips", "5", "2" };
System.out.format("%-15s%-15s%-15s%-15s\n", "Item#", "Item", "Price", "Quantity");
for (int i = 0; i < table.length; i++) {
Object[] row = table[i];
System.out.format("%-15d%-15s%-15s%-15s\n", i, row[0], row[1], row[2]);
}
结果:
Item# Item Price Quantity
0 Pie 2.2 12
1 Cracker 4 15
2 Pop tarts 1 4
3 Sun Chips 5 2
