aboutvariable.java

我自己学习JAVA过程中用键盘敲的代码

package jerryhfb;
public class AboutVariable{
	public static void main(String[] args){
		char m='s';
		int a=4,b=11;
		prt("m in mian="+m);
		prt("a in main="+a);
	    prt("b in main="+b);
	    testVarl(b);
	    float x=1,y=2,z=3;
	    x=testVar2(y,z);
	    prt("x in main is "+x);
	 }
	 
	 
	 static void testVarl(int a){
	 	int b=100;
	 	float m=56.789f;
	 	prt("a in testVar1="+a);
	 	prt("b in testVar1="+b);
	 	prt("m in testVar1="+m);
	 }
	 
	 
	 
	 static float testVar2(float y,float x){
	 	float z=x+y;
	 	prt("x in testVar2 is "+x);
	 	return z;
	 }
	 
	 
	 static void prt(String s){
	 	System.out.println(s);
	 }
	 
}
