public static void main(String args[]){ //String with negative sign String str=”-234″; //An int variable int inum = 110; /* Convert String to int in Java using valueOf() method * the value of variable inum2 would be negative after * conversion */ int inum2 = Integer.valueOf(s...
public static void main(String[] args) { String a = "java"; String b = "java"; String c = "ja" + "va"; } } 1. 2. 3. 4. 5. 6. 7. 变量a、b 和 c 都指向常量池的 “java” 字符串,表达式 “ja” + “va” 在编译期间会把结果值”java”直接赋值给c。所以终于的结果 a==c...
在java中,大家肯定都会遇到int类型转String类型的情形,知其然知其所以然。总结加分析一下,int类型转String类型有下面几种方式: a+”“ String.valueOf(a) Integer.toString(a) 以上三种方法在实际使用过程中都是没有问题的,可是效率上还是有些许区别的,所以写个小程序来对照一下他们的效率: ...
