Java 正在努力正确格式化字符串

我试图迭代一个项目数组，在一个格式化的表中打印出每个项目。 每件商品都有名称、颜色、数量和价格

以下是目前的情况：

for(Item i : itemArray){
System.out.format("%1s%50s%50s", "name = " + i.getName(), "color = " + i.getColor(), "quantity = " + i.getQuantity());
System.out.println();

以下是我需要它的外观：

Name: bike       Color: black       Quantity: 1      Price: 6.00
Name: ladder       Color: blue       Quantity: 150      Price: 9.00
Name: dolphin       Color: orange       Quantity: 15      Price: 100000.00
Name: key       Color: red       Quantity: 12      Price: 510.00

我已经读过api的格式，但仍然无法理解！！！请提供帮助。

格式字符串应为名称：param:

Name: bike       Color: black      Quantity: 1       Price: 6.00
Name: ladder     Color: blue       Quantity: 150     Price: 9.00
Name: dolphin    Color: orange     Quantity: 15      Price: 100000.00
Name: key        Color: red        Quantity: 12      Price: 510.00

更具可读性的方法是只将变量注入格式字符串：

System.out.format("%15s%50s%50s", "name = " + i.getName(), "color = " + i.getColor(), "quantity = " + i.getQuantity());

格式字符串应为名称指定多个字符的宽度%1s:param:

Name: bike       Color: black      Quantity: 1       Price: 6.00
Name: ladder     Color: blue       Quantity: 150     Price: 9.00
Name: dolphin    Color: orange     Quantity: 15      Price: 100000.00
Name: key        Color: red        Quantity: 12      Price: 510.00

更具可读性的方法是只将变量注入格式字符串：

System.out.format("%15s%50s%50s", "name = " + i.getName(), "color = " + i.getColor(), "quantity = " + i.getQuantity());

尝试

System.out.format("Name: %-10s  Color: %-10s Quantity: %-10s Price: %s", ...)

输出

        String fmt = "Name: %-10s Color: %-10s Quantity: %d%n";
        System.out.printf(fmt, "bike", "black", 1);
        System.out.printf(fmt, "ladder", "blue", 1);

尝试

System.out.format("Name: %-10s  Color: %-10s Quantity: %-10s Price: %s", ...)

输出

        String fmt = "Name: %-10s Color: %-10s Quantity: %d%n";
        System.out.printf(fmt, "bike", "black", 1);
        System.out.printf(fmt, "ladder", "blue", 1);
