java - 如何格式化打印输出，以便在 Java 中每行 6 个字符串左对齐？

Question

例如，假设我在 6 个其他字符串之上有 6 个单词/字符串:

tiger   elephant  dog      fish  cat      jaguar
lion    human     manatee  cow   sphinx   cougar

我希望它能这样排列

如果我正确理解您的问题，这里有一个可能适合您需求的简单示例:

String strings[][] = new String[][] {
     {"tiger", "elephant", "dog", "fish", "cat", "jaguar"},
     {"lion", "human", "manatee", "cow", "sphinx", "cougar"}
};

for (String[] line : strings) {
    System.out.printf("%-12s %-12s %-12s %-12s %-12s %-12s\n", 
        line[0], line[1], line[2], line[3], line[4], line[5]);
}

输出:

tiger        elephant     dog          fish         cat          jaguar      
lion         human        manatee      cow          sphinx       cougar
