方法的定义与调动
public static void main(String[] args) {
int max = max(10,20);
System.out.println(max);
}
//比大小
public static int max(int num1,int num2){
int result = 0;
if (num1==num2){
System.out.println("num1==num2");
return 0;//终止方法
}
if (num1>num2){
result = num1;
}else {
result = num2;
}
return result;
}
}
public static void main(String[] args) {
//实际参数：实际调用传递给他参数
int sum = add(1,2);
System.out.println(sum);
test();
}
//加法，形势参数，用来定义作用
public static int add(int a,int b) {
return a + b;
}

if (i%5==0){
System.out.print(i+"\t");
}
if (i%(5*3)==0){ //每行
System.out.println();
//System.out.print("\n");
