intSix = 6 strInt = strSix + repr(intSix) print(strInt) Output: Six6 Using f-strings You can also use f-strings operator to concatenate string and int from python 3.6 onwards. Here is an example. Python 1 2 3 4 5 6 strFour = "four" intFour = 4 strInt = f'{strFour}{in...
常用的方法: int i; // Concatenate "i" with an empty string; conversion is handled for you. String s1 = "" + i; 或者 // The valueOf class method. String s2 = String.valueOf(i); 每个Number子类都包含一个类方法toString(),该方法将其基本类型转换为字符串。 int i; double d; String ...

Literal strings can’t span lines in Java source files, but we can concatenate lines to produce the same effect: String poem = "'Twas brillig, and the slithy toves\n" + " Did gyre and gimble in the wabe:\n" + "All mimsy were the borogoves,\n" + " And the mome raths outgrabe....
