在上面的示例中,我们首先声明了一个长度为5的String数组strArray,然后使用for循环为数组赋值,并最后使用增强for循环打印了数组中的每个元素。 状态图 下面是一个使用mermaid语法表示的状态图,展示了声明String数组并赋值的过程: DeclarationForLoopAssignmentPrintArray 类图 下面是一个使用mermaid语法表示的类图,展示
String[]fruits={"Apple","Banana","Cherry","Date"}; 1. 方法2:使用关键字new 另一种常见的初始化字符串数组的方法是使用new关键字。 String[]colors=newString[3];// 声明一个长度为3的字符串数组colors[0]="Red";// 初始化第一个元素colors[1]="Green";// 初始化第二个元素colors[2]="Blue";...
