Java 对齐柱
我需要在列中显示以下字符串的输出:Java 对齐柱,java,string,indentation,Java,String,Indentation,我需要在列中显示以下字符串的输出: System.out.printf("Weight of Item 1: %10d%n", ITEM_1); System.out.printf("Weight of Item 2: %10d%n", ITEM_2); System.out.printf("Weight of Item 3: %10d%n", ITEM_3); System.out.printf("Total Weight Kilograms: %10d%n", totalWeight
System.out.printf("Weight of Item 1: %10d%n", ITEM_1);
System.out.printf("Weight of Item 2: %10d%n", ITEM_2);
System.out.printf("Weight of Item 3: %10d%n", ITEM_3);
System.out.printf("Total Weight Kilograms: %10d%n", totalWeightKilograms);
我可以将输入到字符串中的变量转移到我想要的位置。我无法获取变量之前的文本格式。基本上,我得到的输出:
Weight of Item 1: 38
Weight of Item 2: 23
Weight of Item 3: 12
Total Weight Pounds: 73
我想要的是:
Weight of Item 1: 38
Weight of Item 2: 23
Weight of Item 3: 12
Total Weight Pounds: 73
我需要字符串的缩进(宽度)。您可以将
项和字符串放入数组中,并指定与最长字符串(22个字符)一样长的格式长度。大概
String[] msg = { "Weight of Item 1", "Weight of Item 2", "Weight of Item 3",
"Total Weight Kilograms" };
int[] items = { ITEM_1, ITEM_2, ITEM_3, totalWeightKilograms };
for (int i = 0; i < msg.length; i++) {
System.out.printf("%22s: %10d%n", msg[i], items[i]);
}
Weight of Item 1: 38
Weight of Item 2: 23
Weight of Item 3: 12
Total Weight Kilograms: 73
