JAVA静态代码块，静态方法，非静态方法 简单比较！~

静态代码块不包含在任何方法体中，当类被载入时自动执行静态代码块，且只被执行一次经，常用于类属性的初始化

静态方法 百度一下

StaticCode 方法如下

package org.dalong.staticblockcode;

/**
* @author HuangDaLong
*
* TODO To change the template for this generated type comment go to Window -
* Preferences - Java - Code Style - Code Templates
*/
public class StaticCode {
protected static String teststring;

static {
System.out.println("call staticcode successful!");
System.out.println("This is teststring: "+teststring );
}

protected static void staticMetho(){
System.out.println("hello,This is Static metho!");
teststring="Static metho made this string!";
}

public String getTeststring() {
return teststring;
}

public void setTeststring(String teststring) {
this.teststring = teststring;
}
}

测试方法如下，大家可以比较一下输出的结果；

package org.dalong.staticblockcode;

/**
* @author HuangDaLong
*
* TODO To change the template for this generated type comment go to Window -
* Preferences - Java - Code Style - Code Templates
*/
public class StaticCodeTest {
public static void main(String args[]) {
/**
* print:call staticcode successful!
* This is tststring:null
*/
new StaticCode();
/**
* no print;
*/
new StaticCode();
/**
* no print;
*/
StaticCode sc = new StaticCode();
/**
* print: null
*/
System.out.println(sc.getTeststring());
/**
* print: hello test;
*/
sc.setTeststring("hello,test!");
System.out.println(sc.getTeststring());
/**
* print:hello,This is Static metho!
*/
StaticCode.staticMetho();
/**
* print:Static metho made this string!
*/
System.out.println(sc.getTeststring());
}
}
