Main.java void main() { int numOfApples = 16; String msg = "There are " + numOfApples + " apples"; System.out.println(msg); } The example uses string concatenation to do int to String conversion. Internally, Java compiler uses StringBuilder to do the conversion. ...
String data = String.valueOf(num); Here, we have used thevalueOf()method of theJava String classto convert the int type variable into a string. Example 2: Type conversion from String to int classMain{publicstaticvoidmain(String[] args){// create string type variableString data ="10"; ...
int i = 15; System.out.println(Integer.toHexString(i));//16进制数输出 System.out.println(Integer.toBinaryString(i));//2进制数输出 System.out.println(Integer.toOctalString(i));//8进制数输出 1. 2. 3. 4. 关于浮点型,java中还提供了一种指数的表达式,例如1.39∗10−121.39∗10−12 ...
