我想知道是否可以將所有字符串數組的結果打印到一個 println 而不是多個。 String[] test1 = { "a", "b", "c" }; String[] test2 = { "a", "B", "c", "D", "e" }; String[] test3 = { "A", "B", "C", "D" }; String[] test4 = { "$", "B", "c", "6", "D", "\n", "E" }; int upperCaseCount1 = countUppercase(test1); //Instead of printing this System.out.println(upperCaseCount1); int upperCaseCount2 = countUppercase(test2); System.out.println(upperCaseCount2); int upperCaseCount3 = countUppercase(test3); System.out.println(upperCaseCount3); int upperCaseCount4 = countUppercase(test4); System.out.println(upperCaseCount4); //am i able to use a single line print? like....my failed attempts here. System.out.println(countUppercase("test1", "test2","test3", "test4");

您可以在 println 中連接結果
int upperCaseCount1 = countUppercase(test1);
int upperCaseCount2 = countUppercase(test2);
int upperCaseCount3 = countUppercase(test3);
int upperCaseCount4 = countUppercase(test4);
System.out.println( upperCaseCount1 +", "+upperCaseCount2 +", "+upperCaseCount3 +", "+upperCaseCount4);
如果您可以使用 printf 代替，您也可以執行以下操作：
System.out.printf( "Results: %d, %d, %d, %d%n", upperCaseCount1, upperCaseCount2, upperCaseCount3, upperCaseCount4);
%d 代表 int，%n 代表換行。簡單的教程。
你也可以使用 StringBuilder。教程。
StringBuilder builder = new StringBuilder("Results: ");
builder.append(countUppercase(test1)).appende(" ").
append(countUppercase(test2)).appende(" ").
append(countUppercase(test3)).appende(" ").
append(countUppercase(test4));
System.out.println( builder);
