Question

代码

package testa;

public class SimpleCalculator {
private static float value1;
private static SimpleCalculator claculator;
private float value2;

public SimpleCalculator(float value12, float value22) {
    // TODO Auto-generated constructor stub
}

public static void main(String[] args) {
    float valuel=0;
    float value2=0;
    if(args.length>=2) {
        value1=  Float.parseFloat(args[0]);
        value2=Float.parseFloat(args[1]);
    }
    else {
        System.out.println("请输入俩个操作数");
        return;

    }
    SimpleCalculator calculator = new SimpleCalculator(value1,value2);
    claculator.printResult();
}
public void SimpleCalculator1(float value1,float value2) {
    this.value1 = value1;
    this.value2 =value2;

}
public void printResult() {
    float addResult = value1 + value2;
    float subResult = value1 - value2;
    float multiResult = value1 * value2;
    float divResult = value1 / value2;
    System.out.println(value1 + "+" +value2+"="+addResult);
    System.out.println(value1 + "-" +value2+"="+subResult);
    System.out.println(value1 + "*" +value2+"="+multiResult);
    System.out.println(value1 + "/" +value2+"="+divResult);
}

}

Arguments中输入11，11

运行后出现

代码没有错误标志
