当我运行一些代码(稍后显示)时,我告诉它检查字符串=="1",如果是,输出"它是1!",否则输出字符串.

码:

double shirt3 = Math.random() * 9;
String shirt2 = Double.toString(shirt3);
char shirt1 = shirt2.charAt(0);
String shirt = Character.toString(shirt1);

if(shirt == "1") {
    System.out.println("It's 1!");
} else {
    System.out.println(shirt);
}

输出:

7
4
8
1
7
1
7
7
6
0
