Example 1: Convert boolean to string using valueOf() class Main { public static void main(String[] args) { // create boolean variables boolean booleanValue1 = true; boolean booleanValue2 = false; // convert boolean to string // using valueOf() String stringValue1 = String.valueOf(...
// convert a given string to // its boolean object using // valueOf() method boolean b1 = Boolean.valueOf(str); // returns boolean object return b1; } // Driver code public static void main(String args[]) { // Given String str String str = "yes" ; // print the result System....

public static void main(String[] args) { // 自动类型转换:小转大,自动转换,啥也不用做 // 1.byte-->short,可以 byte b = 19; short s = b; // short-->byte,不可以自动转换:Type mismatch: cannot convert from short to byte // byte b2=s; System.out.println("s=" + s); // 2.sh...
javac ConvertIntToBoolean.javajavaConvertIntToBoolean 1. 2. 在ConvertIntToBoolean.java中,定义如下: publicclassConvertIntToBoolean{publicstaticvoidmain(String[]args){intnumber=1;// Example int valuebooleanresult=(number!=0);// Convert int to booleanSystem.out.println("The boolean value is: "+...
能够看到String.valueOf是通过调用Integer.toString实现的,也难怪他们的效率如此接近。 他们最后都会调用到convertInt函数中: privatestaticStringconvertInt(AbstractStringBuilder sb,inti){booleannegative=false;StringquickResult=null;if(i <0) { negative =true; ...

如String s = “100”; int i =Integer.parseInt(s)；4.boolean类型不可以转换成其他数据类型。
