a[i++]=1 优先级 java汇编

public class t {
    
    

	public static void main(String[] args) {
    
    
	
		        int[] a= {
    
    0};
		        int i=0;
		       a[i++]=1;
		    }
}

a[i++]=1;
优先级 先赋值再自加
如下
javap反编译

Compiled from "a3.java"
public class r.a3 {
    
    
  public r.a3();
    Code:
       0: aload_0
       1: invokespecial #8                  // Method java/lang/Object."<init>":()V
       4: return

  public static void main(java.lang.String[]);
    Code:
       0: iconst_1
       1: newarray       int
       3: astore_1						
       4: iconst_0			
       5: istore_2				//存变量2上  i
       6: aload_1				//加载数组
       7: iload_2				//加载变量2数值   
       8: iinc          2, 1	//i自加 对数组操作无影响
      11: iconst_1				//存1
      12: iastore				//保存
      13: return
}

a[++i]的话就是先自增再赋值
