java中 if-else for while do-while的用法

java中流程序语句的具体用法 如下：

 

package shark.zd.流程序控制;
// if for while do-while

public class flowDemo {
    public static void main(String[] arges) {
        int a=2,b=1,c=4;
        if(a>b){
            System.out.println("a>b");
            
        }
        else
        {
            System.out.println("a<=b");
            
        }
        //执行符合条件的

        for(int i=0;i<c;i++){
            System.out.println("第"+i+"循环");
        }
        //先判断在执行

        int i=0;
        while(i<c){
            System.out.println("第"+i+"循环");
            i++;
        }
        //先执行在判断

        int j=0;
        do {
            System.out.println("第"+j+"循环");
            j++;
        } while (j<c);
        /**/
    }
}
